[ https://issues.apache.org/jira/browse/FLINK-8909?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16405980#comment-16405980 ]
Chesnay Schepler commented on FLINK-8909:
-----------------------------------------
Have you configured `python.dc.tmp.dir` ? This must be a directory in a distributed filesystem like HDFS.

> Hi,
> i want to run the python application from pyflink.sh with yarn-cluster mode.
> Added "-m yarn-cluster -yn 1 " in pyflink.sh. so my updated pyflink.sh is executing below coomand:
> "$FLINK_BIN_DIR"/flink run -m yarn-cluster -yn 1 -v "$FLINK_ROOT_DIR"/lib/flink-python*.jar "$@"
> Running pyflink.sh:
> ./bin/pyflink.sh /opt/pnda/hitesh/flink-1.4.2/examples/python/WordCount.py
> While running getting below Error:
