Description
When the driver submits a job, DAGScheduler calls sc.broadcast(taskBinaryBytes).
TorrentBroadcast#writeBlocks may fail due to disk problems during blockManager#putBytes.
BlockManager#doPut calls BlockManager#removeBlockInternal to clean up the block.
BlockManager#removeBlockInternal calls DiskStore#remove to clean up blocks on disk.
DiskStore#remove will try to create the directory because the directory does not exist, and an exception will be thrown at this time.
BlockInfoManager#blockInfoWrappers block info and lock not removed.
The catch block in TorrentBroadcast#writeBlocks will call blockManager.removeBroadcast to clean up the broadcast.
Because the block lock in BlockInfoManager#blockInfoWrappers is not released, the dag-scheduler-event-loop thread of DAGScheduler will wait forever.
