Owen O'Malley created HADOOP-18434: -------------------------------------- Summary: Proxy users do not share RPC connections Key: HADOOP-18434 URL: https://issues.apache.org/jira/browse/HADOOP-18434 Project: Hadoop Common Issue Type: Bug Reporter: Owen O'Malley Assignee: Owen O'Malley
When the Hive MetaStore uses Storage-Based Authorization, it needs to perform checks against the NameNode as the query's user. Unfortunately, RPC's ConnectionId uses the UGI's equal & hash functions, which check for the subject's object equality. Thus, we've seen the HMS spawn thousands of threads before they go idle and are eventually closed. If the peak goes over 10k threads the HMS becomes unstable. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
