> Key: HDFS-10429
> URL: https://issues.apache.org/jira/browse/HDFS-10429
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.7.3
> Reporter: Zhiyuan Yang
> Priority: Minor
> Attachments: HDFS-10429.1.patch, HDFS-10429.2.patch, HDFS-10429.3.patch

> Every time I use 'hdfs dfs -put' upload file, this warning is printed:
> {code:java}
> 16/05/18 20:57:56 WARN hdfs.DataStreamer: Caught exception
> java.lang.InterruptedException
> at java.lang.Object.wait(Native Method)
> at java.lang.Thread.join(Thread.java:1245)
> at java.lang.Thread.join(Thread.java:1319)
> at org.apache.hadoop.hdfs.DataStreamer.closeResponder(DataStreamer.java:871)
> at org.apache.hadoop.hdfs.DataStreamer.endBlock(DataStreamer.java:519)
> at org.apache.hadoop.hdfs.DataStreamer.run(DataStreamer.java:696)
> {code}
> The reason is this: originally, DataStreamer::closeResponder always prints a warning about InterruptedException; since HDFS-9812, DFSOutputStream::closeImpl always forces threads to close, which causes InterruptedException.
> A simple fix is to use debug level log instead of warning level.
