When writing data to our hdfs cluster, occasionally I get the following error:

2019-07-09 15:59:07.746 INFO [org.apache.hadoop.hdfs.DataStreamer] (Thread-429765:system) Exception in createBlockOutputStream blk_1074920007_36859614: java.io.EOFException: Unexpected EOF while trying to read response from server

Could this be a timeout issue? If so, any idea which timeout needs to be adjusted? If not, what else could cause this issue?
