-----------------------------
Summary: Fix log message when choosing storage groups for block
movement in balancer
Key: HDFS-16195
URL: https://issues.apache.org/jira/browse/HDFS-16195
Project: Hadoop HDFS
Issue Type: Improvement
Components: balancer & mover
Reporter: Preeti
Correct the log message in line with the logic associated with
moving blocks in chooseStorageGroups() in the balancer. All log lines should
indicate from which storage source the blocks are being moved correctly to
avoid ambiguity. Right now one of the log lines is incorrect:
[https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/balancer/Balancer.java#L555]
which indicates that storage blocks are moved from underUtilized to
aboveAvgUtilized nodes, while it is actually the other way around in the code.
