The root cause is that > spark renew the token(via resource manager) immediately after got one, as > zookeeper don't have a strong consistency guarantee after an update in > cluster, zookeeper client may read a stale value in some followers not synced > with other nodes. > > We apply a patch in spark, but it is still the problem of RBF. Is it possible > for RBF to replace the delegation token store using some other > datasource(redis for example)? -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
