> Key: HDFS-5814
> URL: https://issues.apache.org/jira/browse/HDFS-5814
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.2.0
> Reporter: Ding Yuan
>
> In org/apache/hadoop/hdfs/server/datanode/DataXceiverServer.java, there is
> the following code snippet in the run() method:
> 156: } catch (OutOfMemoryError ie) {
> 157: IOUtils.cleanup(null, peer);
> 158: // DataNode can run out of memory if there is too many transfers.
> 159: // Log the event, Sleep for 30 seconds, other transfers may
> complete by
> 160: // then.
> 161: LOG.warn("DataNode is out of memory. Will retry in 30 seconds.",
> ie);
> 162: try {
> 163: Thread.sleep(30 * 1000);
> 164: } catch (InterruptedException e) {
> 165: // ignore
> 166: }
> 167: }
> Note that InterruptedException is completely ignored. This might not be safe
> since any potential events that lead to InterruptedException are lost?
