Hudson commented on HDFS-9572: ------------------------------ FAILURE: Integrated in Hadoop-trunk-Commit #8990 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/8990/]) HDFS-9572. Prevent DataNode log spam if a client connects on the data (cnauroth: rev 03bab8dea163a9ee45d09d2a0483d45cf6fe57c9) * hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/DataXceiver.java * hadoop-hdfs-project/hadoop-hdfs/CHANGES.txt > Prevent DataNode log spam if a client connects on the data transfer port but > sends no data. > ------------------------------------------------------------------------------------------- > > Key: HDFS-9572 > URL: https://issues.apache.org/jira/browse/HDFS-9572 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode > Reporter: Chris Nauroth > Assignee: Chris Nauroth > Fix For: 2.8.0 > > Attachments: HDFS-9572.001.patch > > > Monitoring tools may choose to check liveness of the DataNode's data transfer > port by connecting to it. The monitoring tool will close the connection > immediately after establishment without sending any data. When this happens, > the DataNode encounters an unexpected EOF and logs a full stack trace. This > creates unneeded noise in the logs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
