-------------------------------
Summary: Erasure Coding: simplify striped block recovery work
computation and add tests
Key: HDFS-8005
URL: https://issues.apache.org/jira/browse/HDFS-8005
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Jing Zhao
Assignee: Jing Zhao
HDFS-7369 adds the functionality to distribute recovery work of striped blocks
to datanodes. There are still some pending issues:
# In {{BlockManager#chooseSourceNode}}, a node is added into {{healthyIndices}}
without checking if its block is live and healthy
# The test {{TestRecoverStripedBlcoks#testMissingStripedBlock}} has not tested
striped blocks because the file is created before setting the storage policy
# In {{computeRecoveryWorkForBlocks}}, instead of using
{{BlockCollection#isStriped}}, we'd better use {{BlockInfo#isStriped}}
