Konstantin Shvachko updated HADOOP-14313: ----------------------------------------- Fix Version/s: (was: 2.7.4) > 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.
