This can be happened when region split.
0.94.x version: write memstore, write hlog, update mvcc.
Client:
{code}
metaTable = new HTable(configuration, HConstants.META_TABLE_NAME);
Result startRowResult = metaTable.getRowOrBefore(searchRow,
HConstants.CATALOG_FAMILY);
if (startRowResult == null) {
throw new TableNotFoundException(Cannot find row in .META. for
table:
+ Bytes.toString(tableName) + , row= +
Bytes.toStringBinary(searchRow));
}
byte[] value = startRowResult.getValue(HConstants.CATALOG_FAMILY,
HConstants.REGIONINFO_QUALIFIER);
if (value == null || value.length == 0) {
throw new IOException(HRegionInfo was null or empty in Meta for +
Bytes.toString(tableName) + , row= +
Bytes.toStringBinary(searchRow));
}
{code}
Server :
HRegion.getClosestRowBefore
{code}
Store store = getStore(family);
// get the closest key. (HStore.getRowKeyAtOrBefore can return null)
KeyValue key = store.getRowKeyAtOrBefore(row);
Result result = null;
if (key != null) {
Get get = new Get(key.getRow());
get.addFamily(family);
result = get(get, null);
}
return result;
{code}
store.getRowKeyAtOrBefore(row); doesn't consider the readPoint, but the get
will, so some value doesn't have commit, getRowKeyAtOrBefore see it, but get
will ignore it, so there is possiable that will return null result.

Anoop Sam John commented on HBASE-6184:
---
{code}
byte[] searchRow =
HRegionInfo.createRegionName(tableName, row, HConstants.NINES,
- false);
+ true);
{code}
This change will affect the look up in the META table?
When searchRow is created with passing newformat=true, it will add the encoded
name also at the end[tableName,row,regionid.encodedname.]. But the
searchRow is used to do metaTable.getRowOrBefore(). Any way after the row we
add HConstants.NINES using which we need to get correct row from META table. I
mean adding this encodedname might not be needed for this lookup
In your issue you are getting the result but in that result the HRegionInfo
seems coming as null only? Do this above change really fix your issue? Do u
facing some other issues?
