CI issues affecting https://github.com/apache/hadoop/pull/8296 but
maybe worth considering.

[Ayush Saxena <ay...@gmail.com>]

Hi Chris,

We’ve been testing Hadoop-3.5.0 with Tez and ran into an issue related
to Jersey, which is being tracked under YARN-11877. I’ve approved the
PR, though there are a few checkstyle warnings that still need to be
addressed.

Is there a chance to include it in the RC?

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Ayush Saxena <ay...@gmail.com>]

Hi Chris,

We’ve been testing Hadoop-3.5.0 with Tez and ran into an issue related
to Jersey, which is being tracked under YARN-11877. I’ve approved the
PR, though there are a few checkstyle warnings that still need to be
addressed.

Is there a chance to include it in the RC?

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Cheng Pan <pa...@gmail.com>]

Hi Chris,

We need both HADOOP-19827 (for security) and HADOOP-19829 (for performance regression) to resolve lz4 issue.

For aliyun connector, I realized that the license issue was bulk fixed in HADOOP-19696 by Steve, so this will not be a 3.5.0 release blocker, but it’s also good if they can remove `-beta` transitive dependencies.

Thanks,
Cheng Pan

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Cheng Pan <pa...@gmail.com>]

Hi Chris,

We need both HADOOP-19827 (for security) and HADOOP-19829 (for performance regression) to resolve lz4 issue.

For aliyun connector, I realized that the license issue was bulk fixed in HADOOP-19696 by Steve, so this will not be a 3.5.0 release blocker, but it’s also good if they can remove `-beta` transitive dependencies.

Thanks,
Cheng Pan

For aliyun connector, I realized that the license issue was bulk fixed in HADOOP-19696 by Steve, so this will not be a 3.5.0 release blocker, but it’s also good if they can remove `-beta` transitive dependencies.

Thanks,
Cheng Pan

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Chris Nauroth <cn...@apache.org>]

I've brought in the following for inclusion in the next RC:

MAPREDUCE-7527: Fix /jobhistory/attempts/ page not rendering attempt
information
YARN-11897: NodeManager REST API backward compatibility with Jersey1

Additionally, I'm planning to include this once it gets a successful
pre-submit run:

HADOOP-19829: Bump lz4-java 1.10.4

Cheng, regarding the vulnerable lz4 jar, will that be resolved by
HADOOP-19829, or is it a different issue?

I'll watch HADOOP-19352 for further updates on the Aliyun dependency issues.

Is there anything else new to consider for inclusion in 3.5.0?

Chris Nauroth

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Steve Loughran <st...@cloudera.com>]

I did a full test of the RC and was happy with it

Testing:
* Used hadoop-release-support to download artifacts, validate signatures
etc.
* used the binaries as my hadoop release for all hadoop fs to cloud, and
cloudstore commands, including gs://

The new gs connector has removed the ability to provide gs credentials by
hadoop config or keystore. This is a PITA. I could get the JSON set up to
work fine, but it is a regression from the bigdata-oss release. Not an
issue if you run in google cloud.


Did a diff -rq to compare contents of the source tar with trunk. That is,
rather than just verify that "something" was built with the source, I
verified that the source tar matches the repo. I will have to trust that
the .class files in the JARs are those which come from the source...that's
a problem I'm worrying about right now: "how do you detect a malicious
release manager?"

Arm linux: good, including native commands once I'd done an apt-get
libssl-dev (as our docs say to do)

Cloudstore didn't compile, but that's because it has integration tests
which extend AbstractFSContractTestBase and of course JUNIT 5 BREAKS
EVERYTHING.

Maybe the release notes of the junit update should mention this. Anyway,
not a blocker as that tool is designed to be built against older releases;
it's a 3.4.0+ build right now.


Side issue:

We will need to a dependency update release of 3.5.0 and 3.4.3 within a few
weeks. I've been using Syft to audit projects (
https://oss.anchore.com/docs/installation/syft/) and it is unhappy about
all the .js stuff as well as things like commons-lang and avro.

We also need to look at Eduard's issues.

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Chris Nauroth <cn...@apache.org>]

I've brought in the following for inclusion in the next RC:

MAPREDUCE-7527: Fix /jobhistory/attempts/ page not rendering attempt
information
YARN-11897: NodeManager REST API backward compatibility with Jersey1

Additionally, I'm planning to include this once it gets a successful
pre-submit run:

HADOOP-19829: Bump lz4-java 1.10.4

Cheng, regarding the vulnerable lz4 jar, will that be resolved by
HADOOP-19829, or is it a different issue?

I'll watch HADOOP-19352 for further updates on the Aliyun dependency issues.

Is there anything else new to consider for inclusion in 3.5.0?

Chris Nauroth

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Chris Nauroth <cn...@apache.org>]

I've brought in the following for inclusion in the next RC:

MAPREDUCE-7527: Fix /jobhistory/attempts/ page not rendering attempt
information
YARN-11897: NodeManager REST API backward compatibility with Jersey1

Additionally, I'm planning to include this once it gets a successful
pre-submit run:

HADOOP-19829: Bump lz4-java 1.10.4

Cheng, regarding the vulnerable lz4 jar, will that be resolved by
HADOOP-19829, or is it a different issue?

I'll watch HADOOP-19352 for further updates on the Aliyun dependency issues.

Is there anything else new to consider for inclusion in 3.5.0?

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Chris Nauroth <cn...@apache.org>]

I've brought in the following for inclusion in the next RC:

MAPREDUCE-7527: Fix /jobhistory/attempts/ page not rendering attempt
information
YARN-11897: NodeManager REST API backward compatibility with Jersey1

Additionally, I'm planning to include this once it gets a successful
pre-submit run:

HADOOP-19829: Bump lz4-java 1.10.4

Cheng, regarding the vulnerable lz4 jar, will that be resolved by
HADOOP-19829, or is it a different issue?

I'll watch HADOOP-19352 for further updates on the Aliyun dependency issues.

Is there anything else new to consider for inclusion in 3.5.0?

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Steve Loughran <st...@cloudera.com>]

I did a full test of the RC and was happy with it

Testing:
* Used hadoop-release-support to download artifacts, validate signatures
etc.
* used the binaries as my hadoop release for all hadoop fs to cloud, and
cloudstore commands, including gs://

The new gs connector has removed the ability to provide gs credentials by
hadoop config or keystore. This is a PITA. I could get the JSON set up to
work fine, but it is a regression from the bigdata-oss release. Not an
issue if you run in google cloud.


Did a diff -rq to compare contents of the source tar with trunk. That is,
rather than just verify that "something" was built with the source, I
verified that the source tar matches the repo. I will have to trust that
the .class files in the JARs are those which come from the source...that's
a problem I'm worrying about right now: "how do you detect a malicious
release manager?"

Arm linux: good, including native commands once I'd done an apt-get
libssl-dev (as our docs say to do)

Cloudstore didn't compile, but that's because it has integration tests
which extend AbstractFSContractTestBase and of course JUNIT 5 BREAKS
EVERYTHING.

Maybe the release notes of the junit update should mention this. Anyway,
not a blocker as that tool is designed to be built against older releases;
it's a 3.4.0+ build right now.


Side issue:

We will need to a dependency update release of 3.5.0 and 3.4.3 within a few
weeks. I've been using Syft to audit projects (
https://oss.anchore.com/docs/installation/syft/) and it is unhappy about
all the .js stuff as well as things like commons-lang and avro.

We also need to look at Eduard's issues.

Side issue:

We will need to a dependency update release of 3.5.0 and 3.4.3 within a few
weeks. I've been using Syft to audit projects (
https://oss.anchore.com/docs/installation/syft/) and it is unhappy about
all the .js stuff as well as things like commons-lang and avro.

We also need to look at Eduard's issues.

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Cheng Pan <pa...@gmail.com>]

Found some dependency issues:

1. HADOOP-19352 upgrades aliyun-sdk-oss from 3.13.2 to 3.18.1, pulls additional transitive deps without properly upgrading LICENSE/NOTICE, see details at [1]
2. vulnerable hadoop-3.5.0/share/hadoop/tools/lib/lz4-java-1.8.0.jar should be excluded, but not, see HADOOP-19747

Hi Chris,
I also haven’t worked much in this part of the codebase and have very
limited experience with the UI layer. But, I tried to debug the issue and
posted a patch that fixes it on my end. I’m not entirely sure whether this
is the best approach or if it only resolves the issue in my setup, but this
is the best I could do to help move things forward.

Let me know what you think. If it looks good, I can create a PR for it. If
something is missing or incorrect, or if you have any feedback, I’m happy
to take another look and continue debugging over the weekend.

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Chris Nauroth <cn...@apache.org>]

I've pulled in the following new patches in preparation for a new RC:

HADOOP-19778: Remove Deprecated WASB Code from Hadoop
HADOOP-19822: Upgrade Avro to 1.11.5
MAPREDUCE-7533: MR AM UI wont be loaded on root path

I still don't have an answer for MAPREDUCE-7527 and would appreciate more
help looking at it. It doesn't repro on 3.4.3, so I'm hoping to find
something from diffing the source.

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Chris Nauroth <cn...@apache.org>]

I've pulled in the following new patches in preparation for a new RC:

HADOOP-19778: Remove Deprecated WASB Code from Hadoop
HADOOP-19822: Upgrade Avro to 1.11.5
MAPREDUCE-7533: MR AM UI wont be loaded on root path

I still don't have an answer for MAPREDUCE-7527 and would appreciate more
help looking at it. It doesn't repro on 3.4.3, so I'm hoping to find
something from diffing the source.

[Chris Nauroth <cn...@apache.org>]

I've pulled in the following new patches in preparation for a new RC:

HADOOP-19778: Remove Deprecated WASB Code from Hadoop
HADOOP-19822: Upgrade Avro to 1.11.5
MAPREDUCE-7533: MR AM UI wont be loaded on root path

I still don't have an answer for MAPREDUCE-7527 and would appreciate more
help looking at it. It doesn't repro on 3.4.3, so I'm hoping to find
something from diffing the source.

Re: [VOTE] Release Apache Hadoop 3.5.0 RC0

[Muralikrishna Dmmkr <mu...@gmail.com>]

Thanks Chris for driving the release,

I have set up a single node environment with the 3.5.0-RC0, and was testing
the JHS UI and found an issue, I have raised MAPREDUCE-7527
<https://issues.apache.org/jira/browse/MAPREDUCE-7527> a few weeks back and
the issue still persists.


Thanks

Thanks Chris for driving the release,

I have set up a single node environment with the 3.5.0-RC0, and was testing
the JHS UI and found an issue, I have raised MAPREDUCE-7527
<https://issues.apache.org/jira/browse/MAPREDUCE-7527> a few weeks back and
the issue still persists.


Thanks
