Subject [jira] [Commented] (HIVE-6900) HostUtil.getTaskLogUrl signature change causes compilation to fail
Date Wed, 23 Apr 2014 22:26:24 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13979014#comment-13979014

Vinod Kumar Vavilapalli commented on HIVE-6900:
-----------------------------------------------

I looked at the issue together with [~jdere]. Haven't reviewed the patch but overall this
can let the compilation pass. The eventual link is used elsewhere in Hive to pull the logs
and do some processing. The link used in the patch will still not work as the URLs changed
completely.

We can do this in two halves
 - Fix compilation for now
 - And then follow up in YARN with a right API that can expose logs to users and change Hive
to use that.

For the compilation fix, we can put back the previous API in YARN via MAPREDUCE-5830 or we
can do the fix as done here in Hive.

Thoughts?

> The signature for HostUtil.getTaskLogUrl has changed between Hadoop-2.3 and Hadoop-2.4.
> Code in shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java works
with Hadoop-2.3 method and causes compilation failure with Hadoop-2.4.
