--------------------------------------
Facing some issue with one UT:Â TestGetClosestAtOrBefore.testUsingMetaAndBinary()
Here, we are writing rows for 3 tables: A, B, C. For each tables, we start
writing rowkeys in some ranges in meta. e.g. first range is ('', key1) and
second is (key2,key3) and so on. While flushing meta, the error is "key not
lexically larger than previous" for second row. Without this patch(with NONE
encoding), this test passes but with default encoding as ROW_INDEX_V1, not sure
what is going wrong while comparing second row with first one.
Sample error: Current Cell is 2nd region of Table A and Last Cell is 1st region
of Table A:
{code:java}
java.io.IOException: Added a key not lexically larger than previous. Current
cell =

> Currently we set both block encoding and compression to NONE.
> ROW_INDEX_V1 has many advantages and (almost) no disadvantages (the hfiles
> are slightly larger about 3% or so). I think that would a better default than
> NONE.
