Hi Gatekeepers.
I'm on Knox 0.12 on HDP 2.5.3 and think I've found a bug with WebHDFS handling
of 'FileAlreadyExists' exceptions.
Whilst working on a fix in WebHdfsHaDispatch, I realized that this dispatch is
not used and DefaultHaDispatch is used based on some logging I added
The `data/services/webhdfs/2.4.0->service.xml` has:
<dispatch
classname="org.apache.hadoop.gateway.hdfs.dispatch.HdfsHttpClientDispatch"
ha-classname="org.apache.hadoop.gateway.hdfs.dispatch.WebHdfsHaDispatch"/>
How is DefaultHaDispatch selected? The changes I need to make are context
isolated to WebHDFS.
Thanks,
Kris
