Note: I am assigning it to myself in the interim so I don't forget. > HCatalog runs a partition listing with an empty filter > ------------------------------------------------------ > > Key: HIVE-5454 > URL: https://issues.apache.org/jira/browse/HIVE-5454 > Project: Hive > Issue Type: Bug > Components: HCatalog > Affects Versions: 0.12.0 > Reporter: Harsh J > Assignee: Brock Noland > Fix For: 0.13.0 > > Attachments: D13317.1.patch, D13317.2.patch, D13317.3.patch > > > This is a HCATALOG-527 caused regression, wherein the HCatLoader's way of > calling HCatInputFormat causes it to do 2x partition lookups - once without > the filter, and then again with the filter. > For tables with large number partitions (100000, say), the non-filter lookup > proves fatal both to the client ("Read timed out" errors from > ThriftMetaStoreClient cause the server doesn't respond) and to the server > (too much data loaded into the cache, OOME, or slowdown). > The fix would be to use a single call that also passes a partition filter > information, as was in the case of HCatalog 0.4 sources before HCATALOG-527. > (HCatalog-release-wise, this affects all 0.5.x users) -- This message was sent by Atlassian JIRA (v6.1#6144)
