Wei-Chiu Chuang commented on HDFS-10429: ---------------------------------------- I have not been able to make progress on this. But for the record, I suspect this bug could result in resource leakage (threads, sockets for example). That said, resource leakage shouldn't be a big issue. Threads will be terminated anyway if CLI command process stops. > DataStreamer interrupted warning always appears when using CLI upload file > --------------------------------------------------------------------------- > > 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 > Assignee: Wei-Chiu Chuang > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
