-----------------------------------

[jira] [Commented] (HBASE-4112) Creating table threw
NullPointerException
Posted by "Ted Yu (JIRA)" <ji...@apache.org>.

Ted Yu commented on HBASE-4112:
-------------------------------
{code}
+ //If regioninfo is null, skip this row
+ if (null == info) {
+ return true;
{code}
I think false should be returned so that it is consistent with code after the above.

-----------------------------------
False means finished scan. True mean continue and process the next record.
In this case , True is better.(my test is also)
// the code segment for metaScan.
for (Result rr : rrs) {
if (processedRows >= rowUpperLimit) {
break done;
}
if (!visitor.processRow(rr))
break done; //exit completely //////////
processedRows++;
