Jeffrey Zhong commented on HBASE-9895: -------------------------------------- class ResultSerialization is extended from Configured. Therefore, when mapreduce initializes those class and configuration will be passed to the new instance automatically(magically). > 0.96 Import utility can't import an exported file from 0.94 > ----------------------------------------------------------- > > Key: HBASE-9895 > URL: https://issues.apache.org/jira/browse/HBASE-9895 > Project: HBase > Issue Type: Bug > Components: mapreduce > Affects Versions: 0.96.0 > Reporter: Jeffrey Zhong > Assignee: Jeffrey Zhong > Attachments: hbase-9895.patch > > > Basically we PBed org.apache.hadoop.hbase.client.Result so a 0.96 cluster > cannot import 0.94 exported files. This issue is annoying because a user > can't import his old archive files after upgrade or archives from others who > are using 0.94. > The ideal way is to catch deserialization error and then fall back to 0.94 > format for importing. -- This message was sent by Atlassian JIRA (v6.1#6144)
