Subject [jira] [Updated] (HADOOP-15059) 3.0 deployment cannot work with old version MR tar ball which break rolling upgrade
Date Wed, 06 Dec 2017 17:02:01 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15059?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated HADOOP-15059:
---------------------------------------------
    Attachment: HADOOP-15059.006.patch

The patch looks good to me.

[~daryn], don't get scared by exception handling!

Uploading a new patch that is same as that of Jason's but with SerializedFormat made static.

The test case failures reported here are unrelated. Though it is surprising how badly the
unit tests are broken - I'll debug them independently and file bugs.

If Jenkins says okay, I'll commit this unless [~daryn] / [~jlowe] say no.

> I think it is due to token incompatiblity change between 2.9 and 3.0. As we claim "rolling
upgrade" is supported in Hadoop 3, we should fix this before we ship 3.0 otherwise all MR
running applications will get stuck during/after upgrade.
