             Summary: ds_hll_sketch() results ascii codec decoding error
                 Key: IMPALA-10012
                 URL: https://issues.apache.org/jira/browse/IMPALA-10012
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Gabor Kaszab



{code:java}
select ds_hll_sketch(l_orderkey) from tpch_parquet.lineitem;

Unknown Exception : 'ascii' codec can't decode byte 0x86 in position 20: ordinal not in range(128)
Traceback (most recent call last):
  File "/home/gaborkaszab/shadow/Impala-upstream/shell/impala_shell.py", line 1183, in _execute_stmt
    for rows in rows_fetched:

    yield [row.split('\t') for row in result.data]
UnicodeDecodeError: 'ascii' codec can't decode byte 0x86 in position 20: ordinal not in range(128)

{code}

Even though there is no point of calling ds_hll_sketch() on its own, we should still make this foolproof and prevent Impala from crashing.
