Íñigo Goiri commented on HDFS-13516:
------------------------------------
A lot of subsequent tests fail with NPE when cleaning up, that should also be
caught.
Another example
[here|https://builds.apache.org/job/hadoop-trunk-win/484/testReport/org.apache.hadoop.ozone/TestMetadataStore/].
The errors are three:
* Could not initialize class org.rocksdb.Options
([example|https://builds.apache.org/job/hadoop-trunk-win/484/testReport/org.apache.hadoop.ozone/TestMetadataStore/testBatchWrite_1_/])
which it must be a Windows error.
* NullPointerException
([example|https://builds.apache.org/job/hadoop-trunk-win/484/testReport/org.apache.hadoop.ozone/TestMetadataStore/testBatchWrite_1__2/])
which is caused by the previous initialization issue, this should be as easy
as check for null in the cleanup.
* C:\Users\jenkins\AppData\Local\Temp\librocksdbjni6432002130619842966.dll: A
dynamic link library (DLL) initialization routine failed
([example|https://builds.apache.org/job/hadoop-trunk-win/484/testReport/org.apache.hadoop.ozone/TestMetadataStore/testDestroyDB_1_/])
which must be related to the first one.
I think this two were introduced in HDFS-12149.
[~cheersyang], [~anu], you guys wrote/committed that part, could you take a
look?
I have two theories:
# RocksDB does not work on Windows and then we should just add an assume
!Windows.
# We are leaving behind some RocksDB and we cannot close them correctly.
In any case, we should check for nulls in the cleanup.
