[jira] [Updated] (PARQUET-2260) Bloom filter bytes size shouldn't be larger than maxBytes size in the configuration

     [ https://issues.apache.org/jira/browse/PARQUET-2260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mars updated PARQUET-2260:
--------------------------
    Summary:  Bloom filter bytes size shouldn't be larger than maxBytes size in the configuration  (was:  Bloom filter bytes size should't be larger than maxBytes size in the configuration)

> If `parquet.bloom.filter.max.bytes` configuration is not a power of 2 value, the size of the bloom filter generated will exceed this value. 
> For example, now if set `parquet.bloom.filter.max.bytes` as 1024*1024+1= 1048577 , the bytes size of bloom filter generated will be 2097152.
> But the correct way is to set this value to the largest power of two less than 1048577. It should be 1024*1024
