> Fix XOR used instead of exponentiation in VerifyReplication backoff
> -------------------------------------------------------------------
>
> Key: HBASE-30486
> URL: https://issues.apache.org/jira/browse/HBASE-30486
> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Reporter: Xiao Liu
> Assignee: Xiao Liu
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0-alpha-1, 2.7.0, 3.1.0, 3.0.1, 2.6.8
>
>
> {\{VerifyReplicationRecompareRunnable}} calculates the retry delay using:
> {code:java}
> sleepMs = sleepMs * (2 ^ reCompareBackoffExponent);
> {code}
> Java's \{{^}} operator performs XOR, not exponentiation. With exponent
> \{{2}}, the multiplier becomes \{{0}}, removing the delay between subsequent
> retries and potentially reporting bad rows before replication catches up.
> Replace XOR with exponentiation to restore the intended backoff behavior.
