Change subject: IMPALA-5789: Add always_false flag in bloom filter ...................................................................... IMPALA-5789: Add always_false flag in bloom filter This patch adds an always_false flag in bloom filters. The flag is set if nothing has been inserted into the bloom filter. HdfsScanner uses this flag to early terminate the scan at file, partition and rowbatch granularities. Testing: A test case is added checking that an always-false runtime filter can filter out files.
