Subject [jira] [Commented] (HADOOP-11470) Remove some uses of obsolete guava APIs from the hadoop codebase
Date Fri, 09 Jan 2015 17:37:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14271581#comment-14271581
] 

Sangjin Lee commented on HADOOP-11470:
--------------------------------------

I ran the hadoop unit tests against guava 16.0.1, and found that TestDFSClientCache.testEviction
fails. I believe it is because the test relies on a particular behavior of guava 11.0.2 (more
aggressive eviction of LocalCache) which is no longer the case in 16.0.1. I'll file a separate
JIRA to fix up the test.

> Along the same vein as HADOOP-11286, there are now several remaining usages of guava
APIs that are now incompatible with a more recent version (e.g. 16).
> This JIRA proposes eliminating those usages. With this, the hadoop code base should run/compile
cleanly even if guava 16 is used for example.
> This JIRA doesn't propose upgrading the guava dependency version however (just making
the codebase compatible with guava 16+).
