-----------------------------------
Summary: Solve SocketTimeoutException#sendPacket() does not record
SocketTimeout exception
Key: HDFS-15936
URL: https://issues.apache.org/jira/browse/HDFS-15936
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: JiangHua Zhu
In SocketTimeoutException#sendPacket(), if a SocketTimeout exception occurs, no
information is recorded here.
try {
......
} catch (IOException e) {
if (e instanceof SocketTimeoutException) {
/*
* writing to client timed out. This happens if the client reads
* part of a block and then decides not to read the rest (but leaves
* the socket open).
*
* Reporting of this case is done in DataXceiver#run
*/
}
}
No records are generated here, which is not conducive to troubleshooting.
We should add a line of warning type log.
