---------------------------------------
Summary: Clicking jstack in ui results in endless empty jstack
dumps
Key: STORM-1542
URL: https://issues.apache.org/jira/browse/STORM-1542
Project: Apache Storm
Issue Type: Bug
Components: storm-core
Affects Versions: 1.0.0
Reporter: Abhishek Agarwal
Assignee: Abhishek Agarwal
Priority: Critical
Resolved path for jstack is
/home/y/share/yjava_jdk/java/jstack which doesn't exist. Exit code returned is
127. When a request for jstack dump is made, a zookeeper entry is made for the
action. Now supervisor keeps on reading this action, executes it and since exit
code is non-zero, doesn't delete the node. So supervisor keeps on trying
forever and the non-existent command results in empty file
{noformat}
$BINPATH/jstack $1 > "$2/${FILENAME}"
{noformat}
