[jira] [Created] (HDFS-2412) Add backwards-compatibility layer for
FSConstants
Add backwards-compatibility layer for FSConstants
-------------------------------------------------
Key: HDFS-2412
URL: https://issues.apache.org/jira/browse/HDFS-2412
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Blocker
Fix For: 0.23.0
HDFS-1620 renamed FSConstants which we believed to be a private class. But currently the public APIs for safe-mode and datanode reports depend on constants in FSConstants. This is breaking HBase builds against 0.23. This JIRA is to provide a backward-compatibility route.

Todd Lipcon commented on HDFS-2412:
-----------------------------------
Can I get a +1 on this small patch in the meantime, so we can get the HBase-on-23 build back to compiling? Then we can consider whether we should just revert the whole thing.

------------------------------
Resolution: Fixed
Hadoop Flags: Reviewed
Status: Resolved (was: Patch Available)
Resolved this in 23 and trunk. If we have more issues related to 1620, let's just revert both this and 1620.

Aaron T. Myers commented on HDFS-2412:
--------------------------------------
I personally do think HDFS-1620 is worth it, and shouldn't be reverted. The patch Todd's provided is very straight-forward, and should fix things up for all down-stream projects that might be affected.
My apologies for not realizing that these private constants are referenced in public APIs when I originally reviewed HDFS-1620. I should have checked for that.

Todd Lipcon commented on HDFS-2412:
-----------------------------------
The problem is that HBase wants to build against both trunk and 20. We could introduce shims into HBase... but I think the deprecation approach is good to have anyway, in case others have similar reliances.
I could also just be convinced to revert HDFS-1620.

[jira] [Commented] (HDFS-2412) Add backwards-compatibility layer
for FSConstants

Arun C Murthy commented on HDFS-2412:
-------------------------------------
The other option is to fix HBase if we really think HDFS-1620 is worth it - of course it'll imply a new HBase release.

> HDFS-1620 renamed FSConstants which we believed to be a private class. But currently the public APIs for safe-mode and datanode reports depend on constants in FSConstants. This is breaking HBase builds against 0.23. This JIRA is to provide a backward-compatibility route.
