xy7 created SPARK-18957: --------------------------- Summary: when WAL time out, loss data Key: SPARK-18957 URL: https://issues.apache.org/jira/browse/SPARK-18957 Project: Spark Issue Type: Bug Components: Block Manager Affects Versions: 1.6.2 Environment: hadoop2.7.1 spark1.6.2 Reporter: xy7 Priority: Critical Fix For: 1.6.2
When sparkStreaming's blockManager writeAheadLog timeout, it cause keepPushBlocks to be stoped, with this warn log "WARN scheduler.ReceiverTracker: Error reported by receiver for stream 0: Error in block pushing thread - java.util.concurrent.TimeoutException: Futures timed out after [30 seconds]". But the receiver continued to get data from MQ, so the data lost. In sparkUI, we would found all the batchs turned to 0 events. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
