Jimmy Xiang commented on HBASE-6184:
------------------------------------
How will this fix the issue? Have you checked the data in the meta table? Does that row have region info?
I think this most likely is a meta table data issue.

[jira] [Commented] (HBASE-6184) HRegionInfo was null or empty in
Meta
Posted by "Anoop Sam John (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-6184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293487#comment-13293487 ]
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?

binlijin commented on HBASE-6184:
---------------------------------
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.

binlijin commented on HBASE-6184:
---------------------------------
0.94
write memstore
write hlog // last a few ms..
update mvcc
Current readPoint = 9;, and the new KeyValue memstoreTS = 10, then the HRegion.getClosestRowBefore is called.
KeyValue key = store.getRowKeyAtOrBefore(row); will see the new KeyValue,
but
Get get = new Get(key.getRow());
get.addFamily(family);
result = get(get, null);
will not see the new KeyValue.
