The structure of the directory in HDFS is
`hdfs://xxx/application_xxxxxx/${shuffleId}/${partitionId}`.
And the `basicPath` in the following code is
`hdfs://xxx/application_xxxxxx/`.
So if spark driver can't send heartbeat to one of the shuffle servers, all
the data of this application will be deleted. @zuston @rickyma
