Summary: ObjectCacheFactory should return null when tez shared object registry is not setup Key: HIVE-17209 URL: https://issues.apache.org/jira/browse/HIVE-17209 Project: Hive Issue Type: Bug Reporter: Rajesh Balamohan Priority: Minor HIVE-15269 introduced dynamic min/max bloom filter ("hive.tez.dynamic.semijoin.reduction=true"). This needs to access ObjectCache and in tez, ObjectCache can only be created by {{TezProcessor}}. In the following case {{AM --> splits --> OrcInputFormat.pickStripes::evaluatePredicateMinMax --> DynamicValue.getLiteral --> objectCache access}}, AM ends up throwing lots of NPE since AM has not created ObjectCache. Orc reader catches these exceptions, skips PPD and proceeds further. For e.g, in Q95 it ends up throwing ~30,000 NPE before completing split information. ObjectCacheFactory should return null when tez shared object registry is not setup. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
