> ORC bloom filter is supported by the version of hive used in Spark 1.5.2.
> However, when trying to create orc file with bloom filter option, it does not
> make use of it.
> E.g, following orc output does not create the bloom filter even though the
> options are specified.
> {noformat}
> Map<String, String> orcOption = new HashMap<String, String>();
> orcOption.put("orc.bloom.filter.columns", "*");
> hiveContext.sql("select * from accounts where
> effective_date='2015-12-30'").write().
> format("orc").options(orcOption).save("/tmp/accounts");
> {noformat}
