Description

HDFS-10826 fix fsck for corrupt EC files if no parameters are specified.

However, if I change the test case added in HDFS-10826 (TestFsck#testFsckCorruptECFile) to run "fsck -list-corruptfileblocks", the same test test failed because fsck reports no corrupt files.

Interestingly, if I run "fsck -files -blocks -replicaDetails" then the test passed and shows the corrupt file.

Need to fix the discrepancy.
