[jira] Commented: (HADOOP-4533) HDFS client of hadoop 0.18.1 and
HDFS server 0.18.2 (0.18 branch) not compatible
[ https://issues.apache.org/jira/browse/HADOOP-4533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643279#action_12643279 ]
Owen O'Malley commented on HADOOP-4533:
---------------------------------------
This seems to have been caused by HADOOP-4116, based on Nicholas' testing.
> HDFS client of hadoop 0.18.1 and HDFS server 0.18.2 (0.18 branch) not compatible

> Key: HADOOP-4533
> URL: https://issues.apache.org/jira/browse/HADOOP-4533
> Project: Hadoop Core
> Issue Type: Bug
> Components: dfs
> Affects Versions: 0.18.1
> Reporter: Runping Qi
>
> Not sure whether this is considered as a bug or is an expected case.
> But here are the details.
> I have a cluster using a build from hadoop 0.18 branch.
> When I tried to use hadoop 0.18.1 dfs client to load files to it, I got the following exceptions:
> hadoop --config ~/test dfs -copyFromLocal gridmix-env /tmp/.

> This problem has a severe impact on Pig 2.0, since it is pre-packaged with hadoop 0.18.1 and will use
> Hadoop 0.18.1 dfs client in its interaction with hadoop cluster.
> That means that Pig 2.0 will not work with the to be released hadoop 0.18.2
