Subject [jira] [Commented] (HIVE-5138) Streaming - Web HCat API
Date Mon, 09 Sep 2013 18:46:56 GMT


Eugene Koifman commented on HIVE-5138:

[~roshan_naik] A couple of comments on this patch:
1. All delegators in WebHCat take the 'user' as determined by and use that to
make secure calls to JobTrakcer, HDFS etc.  HCatStreamingDelegator ignores it.  Why is that?
2. Most operations in HCatStreamingDelegator do multiple things (like modify metadata, create
some HDFS file, etc.).  It sounds like every one of these operations should be atomic.  For
example, say for some reason 2 identical calls to partitionRoll() happen at the same time.
 How is this atomicity achieved?
