Enis Soztutar updated HBASE-10859:
----------------------------------
Attachment: hbase-10859_v2.patch
Here is a v2 patch, which apart from the v1 patch:
- Adds a unit test for doing concurrent compaction+flushes in primary, and
reading and reopening from secondary. This test reveals two minor issues as
below which are fixed in this patch as well.
- compute hdfs block distribution does not work for hfile link if the link
location is moved in between getting the file status and getting the block
locations. We now retry on FileNotFoundException
- On region open, the secondaries does not replay the recovered edits file
(since it causes a flush and deletes the log files). Also .tmp directory is not
removed.
> HStore.openStoreFiles() should pass the StoreFileInfo object to
> createStoreFileAndReader()

> The region fails to open for the region replica, because at this time, the
> primary region is performing a compaction. The file is moved to the archive
> directory in between listing of store files and opening those store files
> from the secondary.
> The secondary region should able to deal with this through usage of
> StoreFileInfo and HFile, but since we are reconstructing the StoreFileInfo
> object twice between HStore.openStoreFiles() and createStoreFileAndReader()
> we are getting this exception.
