Szalay-Beko Mate commented on YARN-9783: ---------------------------------------- [~ste...@apache.org], what do you think? > Remove low-level zookeeper test to be able to build Hadoop against zookeeper > 3.5.5 > ---------------------------------------------------------------------------------- > > Key: YARN-9783 > URL: https://issues.apache.org/jira/browse/YARN-9783 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Szalay-Beko Mate > Priority: Major > > ZooKeeper 3.5.5 release is the latest stable one. It contains many new > features (including SSL related improvements which are very important for > production use; see [the release > notes|https://zookeeper.apache.org/doc/r3.5.5/releasenotes.html]). Yet there > should be no backward incompatible changes on the API, so the applications > using ZooKeeper clients should be built against the new zookeeper without any > problem and the new ZooKeeper client should work with the older (3.4) servers > without any issue, at least until someone is start to use new functionality. > The aim of this ticket is not to change the ZooKeeper version used by Hadoop > YARN yet, but to enable people to rebuild and test Hadoop with the new > ZooKeeper version. > Currently the Hadoop build (with ZooKeeper 3.5.5) fails because of a YARN > test case: > [TestSecureRegistry.testLowlevelZKSaslLogin()|https://github.com/apache/hadoop/blob/a0da1ec01051108b77f86799dd5e97563b2a3962/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-registry/src/test/java/org/apache/hadoop/registry/secure/TestSecureRegistry.java#L64]. > This test case seems to use low-level ZooKeeper internal code, which changed > in the new ZooKeeper version. Although I am not sure what was the original > reasoning of the inclusion of this test in the YARN code, I propose to remove > it, and if there is still any missing test case in ZooKeeper, then let's > issue a ZooKeeper ticket to test this scenario there. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
