------------------------------------
Summary: 2-way commit did not happen when WRITE failure injected
in one of the datanodes of a piepeline
Key: HDDS-3229
URL: https://issues.apache.org/jira/browse/HDDS-3229
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Nilotpal Nandi
This is an extension of bug HDDS-3214.
steps taken :
1) Mounted noise injection FUSE on all datanodes
2) Selected 1 datanode from each open pipeline (factor=3)
3) Injected WRITE FAILURE noise with error code - ENOENT on "hdds.datanode.dir"
path of list of datanodes selected in step 2)
4) start PUT key operation of size 32 MB.
Observation :
----------------
PUT key operation failed.
As there is a WRITE failure in one of the datanodes in the pipeline, 3 way
commit should fail.
But it should proceed with 2-way commit and the operation should have been
successful.
