So, if the active NN has frozen (but not actually crashed), this call can hang forever. This can then potentially prevent the standby from becoming active. > This may actually considered a side effect of HADOOP-6762 -- if the RPC were interruptible, that would also fix the issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-dev-help@hadoop.apache.org
