churro morales updated HBASE-15321: ----------------------------------- Status: Patch Available (was: Open) > Ability to open a HRegion from hdfs snapshot. > --------------------------------------------- > > Key: HBASE-15321 > URL: https://issues.apache.org/jira/browse/HBASE-15321 > Project: HBase > Issue Type: New Feature > Affects Versions: 2.0.0, 3.0.0, 1.5.0 > Reporter: churro morales > Assignee: churro morales > Attachments: HBASE-15321.patch, HBASE-15321.v01.patch, > HBASE-15321.v02.patch > > > Now that hdfs snapshots are here, we started to run our mapreduce jobs over > hdfs snapshots. The thing is, hdfs snapshots are read-only point-in-time > copies of the file system. Thus we had to modify the section of code that > initialized the region internals in HRegion. We have to skip cleanup of > certain directories if the HRegion is backed by a hdfs snapshot. I have a > patch for trunk with some basic tests if folks are interested. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
