------------------------------
2., unless you think the getHRegionInfoOrNull to awkward to use and that we
should get rid of it and turn all calls to getHREgionInfos into
getHRegionInfoOrNulls.
> NPE in HTable.getRegionsInfo()
> ------------------------------

> Key: HBASE-3731
> URL: https://issues.apache.org/jira/browse/HBASE-3731
> Project: HBase
> Issue Type: Bug
> Reporter: Liyin Tang
>
> In HTable.getRegionInfo
> <code>
> HRegionInfo info = Writables.getHRegionInfo(
> rowResult.getValue(HConstants.CATALOG_FAMILY,
> HConstants.REGIONINFO_QUALIFIER));
> </code>
> But the rowResult.getValue() may return null, and Writables.getHRegionInfo
> will throw NullPoinException when the parameter is null.
> 2 fixes here:
> 1) In Writables.getHRegionInfo(). We need to check whether the data is null
> before using data.length.
> 2)<code>
> HRegionInfo info = Writables.getHRegionInfoOrNull(
> rowResult.getValue(HConstants.CATALOG_FAMILY,
> HConstants.REGIONINFO_QUALIFIER));
> if(info == null)
> return false
> </code>
> Any thoughts?
