The constructor for {{FairCallQueue}} takes the same parameter {{capacity}} as the default CallQueue implementation, and allocates all its sub-queues of size {{capacity}}. With 4 levels of priority (sub-queues) by default it results in the total callQueue size 4 times larger than it should be based on the configuration. > {{capacity}} should be divided by the number of sub-queues at some place. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
