-----------------------------
Summary: Resolve ICAST findbugs warnings in current codes
Key: HBASE-15117
URL: https://issues.apache.org/jira/browse/HBASE-15117
Project: HBase
Issue Type: Bug
Reporter: Yu Li
Priority: Minor
In [findbugs
output|https://builds.apache.org/job/PreCommit-HBASE-Build/120/artifact/patchprocess/branch-findbugs-hbase-server-warnings.html#Warnings_STYLE]
of recent build, we could see ICAST warnings (Result of integer multiplication
cast to long) on Compactor and ExportSnapshot
>From the code I guess the design is to avoid multiplication result to
>overflow, however current implementation cannot achieve the goal. For example,
>output of below codes
{code}
int i = 1000000;
long a = i * i;
long b = (long) i * i;
System.out.println(a);
System.out.println(b);
{code}
will be
{noformat}
-727379968
1000000000000
{noformat}
Will make some minor changes to resolve this issue.
