> Use CRC tables to speed up galoisFieldMultiply in CrcUtil
> ---------------------------------------------------------
>
> Key: HADOOP-19012
> URL: https://issues.apache.org/jira/browse/HADOOP-19012
> Project: Hadoop Common
> Issue Type: Improvement
> Components: util
> Reporter: Tsz-wo Sze
> Assignee: Tsz-wo Sze
> Priority: Major
> Labels: pull-request-available
>
> CrcUtil.galoisFieldMultiply(p, q, m) supports multiplying two polynomials p,
> q modulo any modulus polynomial m over GF(2). Since the method is used for
> CRC calculations, the modulus polynomial m is restricted to either the
> GZIP_POLYNOMIAL or the CASTAGNOLI_POLYNOMIAL. We may use CRC tables in
> PureJavaCrc32/PureJavaCrc32C to speed up the computation.
