Subject [jira] [Commented] (HBASE-13149) HBase MR is broken on Hadoop 2.5+ Yarn
Date Mon, 16 Mar 2015 22:54:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14364135#comment-14364135

Enis Soztutar commented on HBASE-13149:

bq. As for client API compatibility... Good point. I do find that a stretch, though, since
this just happens to be a library that we ship with and that a user might have compiled against
and that might break compilation now. If that is the only concern I honestly think we can
make the change.
It is our API that we are making promises for "source compatibility", not other's API coming
through as a dependency. I thought the "dependency compatibility" is for that, and hence my
argument for dropping support for it in minor versions.

> The problem seems to be the jackson jar version.  HADOOP-10104 updated jackson version
to 1.9.13.  YARN-2092 reported a problem as well.
> HBase is using jackson 1.8.8. This version of the jar in the classpath seem to cause
the problem.
> Should we upgrade to jackson 1.9.13?
