Description

Impala fails to read TEXT/LZO tables when max_scan_range_length is set to a small value.

impala-shell.sh -i localhost -q "set max_scan_range_length=1; select * from functional_text_lzo.tinytable"
Connected to localhost:21000
MAX_SCAN_RANGE_LENGTH set to 1
Query: select * from functional_text_lzo.tinytable
Query finished, fetching results ...
ERROR: No block index for hdfs://localhost:20500/test-warehouse/tinytable_text_lzo/000000_0.lzo after offset: 41
ERROR: Invalid query handle
Could not execute command: select * from functional_text_lzo.tinytable

Will disable the scan range length tests against lzo until this is resolved.
