Andrew Purtell commented on HBASE-5963:
---------------------------------------
Hadoop 2.0 changes the clientFinalizer from a Thread to a Runnable. We can catch the ClassCastException and create a Thread with that Runnable, and then call ShutdownHookManager by reflection to unregister the clientFinalizer.

Andrew Purtell commented on HBASE-5963:
---------------------------------------
The bulk of the work here isn't managing the shutdown hook, it is dealing with the different Hadoop versions through special casing and reflection. If you'd like to make a more involved change here that introduces a shim and works more nicely with 2.0, that would be great. I opted for lower risk of breaking 1.0, CDH, etc. It's definitely a debatable choice.

[jira] [Updated] (HBASE-5963) ClassCastException:
FileSystem$Cache$ClientFinalizer cannot be cast to Thread
Posted by "Andrew Purtell (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-5963?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Purtell updated HBASE-5963:
----------------------------------
Attachment: HBASE-5963.patch
Latest patch seems to do the right thing according to unit tests without breaking older functionality.
However, what we are doing here is yanking the HDFS client finalizer Runnable away from the Hadoop 2.x ShutdownHookManager and adding it -- wrapped with our existing strategy here -- to the Runtime shutdown hook list, to perhaps run concurrently with the rest of the ShutdownHookManager registered Runnables. I don't think this less problematic than the rest of this horrible code. The solution is, someday, to leave Hadoop 1.x behind and transition to using the 2.x ShutdownHookManager.

[jira] [Commented] (HBASE-5963) ClassCastException:
FileSystem$Cache$ClientFinalizer cannot be cast to Thread
Posted by "Andrew Purtell (JIRA)" <ji...@apache.org>.

Andrew Purtell commented on HBASE-5963:
---------------------------------------
These test pass with the "v1" patch. I think the difference is in Hadoop 1.x there is a cacheFinalizer per filesystem impl, but in 2.x there is one for all filesystems (for the user).

---------------------------------------
Ignore Hadoop QA. To verify the patch, you'll have to run tests locally with
{noformat}
mvn -PlocalTests -Psecurity \
-Dhadoop.profile=23 -Dhadoop.version=2.0.0-SNAPSHOT \
clean test
{noformat}
Note that all of the MR based tests are currently broken, I opened HBASE-5966.

----------------------------------------------------------------
Latest patch seems to do the right thing according to unit tests without breaking older functionality.
However, what we are doing here is yanking the HDFS client finalizer Runnable away from the Hadoop 2.x ShutdownHookManager and adding it -- wrapped with our existing strategy here -- to the Runtime shutdown hook list, to perhaps run concurrently with the rest of the ShutdownHookManager registered Runnables. I don't think this more problematic than the rest of this horrible code. The solution is, someday, to leave Hadoop 1.x behind and transition to using the 2.x ShutdownHookManager.

Did you run unit tests with -Dhadoop.profile=23 and -Dhadoop.version=2.0.0-snapshot ? They pass except for the MR ones? And tests pass for Hadoop 1?

[jira] [Commented] (HBASE-5963) ClassCastException:

Zhihong Yu commented on HBASE-5963:
-----------------------------------
I wasn't able to reproduce the test failure:
{code}
mvn test -Dhadoop.profile=23 -Dhadoop.version=2.0.0-SNAPSHOT -PlocalTests -Dtest=TestRegionRebalancing
...
Running org.apache.hadoop.hbase.TestRegionRebalancing
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 30.049 sec
...
[INFO] Total time: 54.616s
{code}
Also, the 'Failed suppression of fs shutdown hook' message should be at line 205 of ShutdownHook.java
@Andy:
Please give me a little more clue.

[jira] [Issue Comment Edited] (HBASE-5963) ClassCastException:

----------------------------------------------------------------
The attached patch gets past the problem but I'm not able to test it yet due to another issue I'm about to file another JIRA for.
Edit: I mean, I can see that it gets past the ClassCastException, and the ShutdownHookManager removes the client finalizer successfully, but I have not yet been able to observe if normal RS shutdown is ok.

[jira] [Commented] (HBASE-5963) ClassCastException:
FileSystem$Cache$ClientFinalizer cannot be cast to Thread
Posted by "Zhihong Yu (JIRA)" <ji...@apache.org>.

Zhihong Yu commented on HBASE-5963:
-----------------------------------
@Andy:
I am running the following on Linux:
{code}
nohup mvn test -Dhadoop.profile=23 -Dhadoop.version=2.0.0-SNAPSHOT -PrunAllTests > suite.txt &
{code}
Will check results tomorrow.
For hadoop 1.0, PreCommit build 1808 would tell us the results.
For ShutdownHookManagerV2.addShutdownHook(), current code reflects what was in patch v1. Your suggestion is plausible.
