Since this PR includes two types of changes, I think that it would be good to split this into two PRs if both of them are necessary. |

Originally this pr is for SPARK-21902 which i think calling for DiskBlockManager.getFile should be uniform and we should print root cause when call 'Blockmanager#doPut' failed.
Since @kiszk commented,i split this one into an other pr PR-19171
