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 Server.java 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?
