Chen Zhang reassigned HDFS-14830: --------------------------------- Assignee: Chen Zhang > The calculation of DataXceiver count is not accurate > ---------------------------------------------------- > > Key: HDFS-14830 > URL: https://issues.apache.org/jira/browse/HDFS-14830 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Chen Zhang > Assignee: Chen Zhang > Priority: Major > > DataNode use threadGroup.activeCount() as the number of DataXceiver, it's not > accurate since threadGroup includes not only DataXceiver thread and > DataXceiverServer thread, PacketResponder thread and BlockRecoveryWorker > thread is also in the same threadGroup. > In the worst case, the reported DataXceiver count maybe double of actual > count(e.g. all DataXceiver process write block operation, they create same > number of PacketResponder thread at the same time). -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
