[jira] [Created] (HDFS-2553) BlockPoolSliceScanner spinning in loop
BlockPoolSliceScanner spinning in loop
--------------------------------------
Key: HDFS-2553
URL: https://issues.apache.org/jira/browse/HDFS-2553
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node
Affects Versions: 0.23.0, 0.24.0
Reporter: Todd Lipcon
Priority: Critical
Playing with trunk, I managed to get a DataNode in a situation where the BlockPoolSliceScanner is spinning in the following loop, using 100% CPU:
at org.apache.hadoop.hdfs.server.datanode.DataNode$BPOfferService.isAlive(DataNode.java:820)
at org.apache.hadoop.hdfs.server.datanode.DataNode.isBPServiceAlive(DataNode.java:2962)
at org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner.scan(BlockPoolSliceScanner.java:625)
at org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner.scanBlockPoolSlice(BlockPoolSliceScanner.java:614)
at org.apache.hadoop.hdfs.server.datanode.DataBlockScanner.run(DataBlockScanner.java:95)
