------------------------------
Summary: Erasure Coding: Skip encoding the data cells if all the
parity data streamers are failed for the current block group
Key: HDFS-9261
URL: https://issues.apache.org/jira/browse/HDFS-9261
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Rakesh R
Assignee: Rakesh R
Priority: Minor
{{DFSStripedOutputStream}} will continue writing with minimum number
(dataBlockNum) of live datanodes. It won't replace the failed datanodes
immediately for the current block group. Consider a case where all the parity
data streamers are failed, now it is unnecessary to encode the data block cells
and generate the parity data. This is a corner case where it can skip
{{writeParityCells()}} step.
