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?
