Matteo Bertozzi commented on HBASE-8156: ---------------------------------------- overall looks good. Just worth investigating if FSUtils.create() is implemented in the proper way I remember that if you're calling fs.getDefaultReplication() or fs.getDefaultBlockSize() with ViewFS you end up with an exception (because they are not implemented) > Support for Namenode HA for non-idempotent operations > ----------------------------------------------------- > > Key: HBASE-8156 > URL: https://issues.apache.org/jira/browse/HBASE-8156 > Project: HBase > Issue Type: Sub-task > Components: Filesystem Integration > Affects Versions: 0.95.0 > Reporter: Himanshu Vashishtha > Assignee: Himanshu Vashishtha > Fix For: 0.98.0 > > Attachments: HBase-8156-trunk-v1.patch > > > In hadoop 2 HA, non-idempotent operations are not retried at the hdfs side. > This is by design as retrying a non-idempotent operation might not be a good > design choice for some use case. > HBase needs to handle the retries for such operations at its end. > With HBase-7806, there is already some work going on for file system > abstractions. There, HReginFileSystem sits as an abstraction between region > and FS. This jira is a move in the same direction, where it adds retry > functionality for non-idempotent calls such as create, rename and delete in > HRegionFileSystem class. -- This message is automatically generated by JIRA.
