-----------------------------------------------------------------

I have a reproduce on latest Drill master version:
{code}
0: jdbc:drill:> select myhbase.cf1 from hbase. myhbase;
+--------------------------+
|           cf1            |
+--------------------------+
| {"col1":"c29tZWRhdGE="}  |
| {"col1":"c29tZWRhdGE="}  |
| {"col1":"c29tZWRhdGE="}  |
+--------------------------+
3 rows selected (0.169 seconds)
0: jdbc:drill:> select myhbase.cf1 from hbase. myhbase;
+------+
| cf1  |
+------+
+------+
No rows selected (0.188 seconds)
{code}

Without fde0a1df1734e0 commit (fix for DRILL-5546) there is no this issue.


was (Author: vitalii):
[~prasadns14] Looks like the result is correct. Please verify:
{code}
0: jdbc:drill:> select * from hbase.myhbase;
+--------------+--------------------------+
|   row_key    |           cf1            |
+--------------+--------------------------+
| [B@3486f312  | {"col1":"c29tZWRhdGE="}  |
| [B@12e0f043  | {"col1":"c29tZWRhdGE="}  |
| [B@6dbdc863  | {"col1":"c29tZWRhdGE="}  |
+--------------+--------------------------+
3 rows selected (0.322 seconds)
0: jdbc:drill:> select convert_from(row_key, 'UTF8') as id, 
convert_from(myhbase.cf1.col1, 'UTF8') col1 from hbase. myhbase;
+-----+-----------+
| id  |   col1    |
+-----+-----------+
| c   | somedata  |
| a   | somedata  |
| b   | somedata  |
+-----+-----------+
3 rows selected (0.262 seconds)
{code}

Note: the above result is the same for Drill-1.10 and Drill-1.12 master version.
