----------------------------------
Summary: add mounting of HDFS Short-Circuit path for docker
containers
Key: YARN-6494
URL: https://issues.apache.org/jira/browse/YARN-6494
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Reporter: Jaeboo Jeong
Currently there is a error message about HDFS short-circuit when docker
container start.
{code}
WARN [main] org.apache.hadoop.hdfs.shortcircuit.DomainSocketFactory: error
creating DomainSocket
java.net.ConnectException: connect(2) error: No such file or directory when
trying to connect to ‘xxxxxxx’
at org.apache.hadoop.net.unix.DomainSocket.connect0(Native Method)
at org.apache.hadoop.net.unix.DomainSocket.connect(DomainSocket.java:250)

org.apache.hadoop.hdfs.shortcircuit.DomainSocketFactory.createSocket(DomainSocketFactory.java:164)
at
org.apache.hadoop.hdfs.BlockReaderFactory.nextDomainPeer(BlockReaderFactory.java:752)
...
{code}
if dfs.client.read.shortcircuit is true and dfs.domain.socket.path isn't equal
“”, we need to mount volume for short-circuit path.
