Masatake Iwasaki updated HDFS-15037: ------------------------------------ Target Version/s: 2.10.3 (was: 2.10.2) > Encryption Zone operations should not block other RPC calls while retreiving > encryption keys. > --------------------------------------------------------------------------------------------- > > Key: HDFS-15037 > URL: https://issues.apache.org/jira/browse/HDFS-15037 > Project: Hadoop HDFS > Issue Type: Bug > Components: encryption, namenode > Affects Versions: 2.10.0 > Reporter: Konstantin Shvachko > Priority: Major > > I believe it was an intention to avoid blocking other operations while > retrieving keys with holding {{FSDirectory.dirLock}}. But in reality all > other operations enter first {{FSNamesystemLock}} then {{dirLock}}. So they > are all blocked waiting for the key. > We see substantial increase in RPC wait time ({{RpcQueueTimeAvgTime}}) on > NameNode when encryption operations are intermixed with regular workloads. -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
