### Description of PR Current , there is no retry policy If we meet IOExcetion when creating block reader to read EC file. Suppose below case (using RS-6-3-1024k): The first 4 to 6 data blocks' datanodes are very busy at the same time, createBlockReader will timeout. This will cause read failure, we should make EC support retry mechanism to mitigate read failure. ### How was this patch tested? Add an unit test to reproduce. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
