> Replace/improve Hadoop's byte[] comparator
> ------------------------------------------
>
> Key: HADOOP-14313
> URL: https://issues.apache.org/jira/browse/HADOOP-14313
> Project: Hadoop Common
> Issue Type: Improvement
> Components: common
> Affects Versions: 2.7.4
> Reporter: Vikas Vishwakarma
> Attachments: HADOOP-14313.001.patch,
> HADOOP-14313.branch-2.7.001.patch, HADOOP-14313.branch-2.7.002.patch
>
>
> Hi,
> Recently we were looking at the Lexicographic byte array comparison in HBase.
> We did microbenchmark for the byte array comparator of HADOOP (
> https://github.com/hanborq/hadoop/blob/master/src/core/org/apache/hadoop/io/FastByteComparisons.java#L161
> ) , HBase Vs the latest byte array comparator from guava (
> https://github.com/google/guava/blob/master/guava/src/com/google/common/primitives/UnsignedBytes.java#L362
> ) and observed that the guava main branch version is much faster.
> Specifically we see very good improvement when the byteArraySize%8 != 0 and
> also for large byte arrays. I will update the benchmark results using JMH for
> Hadoop vs Guava. For the jira on HBase, please refer HBASE-17877.
