Rushabh S Shah commented on HDFS-11885: --------------------------------------- I tried to upmerge my internal 2.8 version of patch to trunk and it is conflicting with HDFS-11210. After HDFS-11210, the _asynchronus_ behavior of background refill thread is no longer synchronous. Created HDFS-12667 to fix that. > createEncryptionZone should not block on initializing EDEK cache > ---------------------------------------------------------------- > > Key: HDFS-11885 > URL: https://issues.apache.org/jira/browse/HDFS-11885 > Project: Hadoop HDFS > Issue Type: Bug > Components: encryption > Affects Versions: 2.6.5 > Reporter: Andrew Wang > Assignee: Andrew Wang > Attachments: HDFS-11885.001.patch, HDFS-11885.002.patch, > HDFS-11885.003.patch, HDFS-11885.004.patch > > > When creating an encryption zone, we call {{ensureKeyIsInitialized}}, which > calls {{provider.warmUpEncryptedKeys(keyName)}}. This is a blocking call, > which attempts to fill the key cache up to the low watermark. > If the KMS is down or slow, this can take a very long time, and cause the > createZone RPC to fail with a timeout. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
