java IOException :Failed to create local dir in /tmp/blockmgr*
I was trying to run a long running Spark Job. After few hours of execution, I get exception below :
Caused by: java.io.IOException: Failed to create local dir in /tmp/blockmgr-bb765fd4-361f-4ee4-a6ef-adc547d8d838/28
Tried to get around it by checking:
Permission issue in /tmp dir. The spark server is not running as root. but /tmp dir should be writable to all users.
/tmp Dir has enough space.
Assuming that you are working with several nodes, you'll need to check every node participate in the spark operation (master/driver + slaves/nodes/workers).
Please confirm that each worker/node have enough disk space (especially check /tmp folder), and right permissions.
