Summary: cleanup issues in LLAP IO after cache OOM Key: HIVE-20247 URL: https://issues.apache.org/jira/browse/HIVE-20247 Project: Hive Issue Type: Bug Reporter: Prasanth Jayachandran Assignee: Sergey Shelukhin LLAP IO creates unallocated buffer objects inside the read-related data structures, then allocates them in bulk, then decompresses into them and increfs them. If allocate or decompress steps fail, it's hard for the higher-level cleanup to tell what the state of the buffers in the read-related structures is - they may be unallocated, allocated but not incref-ed, or incref-ed. Some cleanup paths only deal with the latter case, resulting in bugs. This only happens on one paths, others allocate and use buffers in a single place. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
