Mars updated PARQUET-2260:
--------------------------
Description:
Before this PR: 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, if set {{parquet.bloom.filter.max.bytes}} as 1024 * 1024+1=
1048577 , the bytes size of bloom filter generated will be 1024 * 1024 * 2 =
2097152. This does not match the definition of the parameter
After this PR: If {{parquet.bloom.filter.max.bytes}} configuration is not a
power of 2, and the size of {{parquet.bloom.filter.max.bytes}} is the final
bloom filter bytes size.

Before this PR: 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 1024 * 1024
* 2 = 2097152. This does not match the definition of the parameter
After this PR: set this value to the largest power of two less than
{{parquet.bloom.filter.max.bytes}} and It should be 1024 * 1024
> Bloom filter bytes size shouldn't be larger than maxBytes size in the
> configuration
