Subject [jira] [Commented] (HBASE-13262) ResultScanner doesn't return all rows in Scan
Date Thu, 26 Mar 2015 18:43:55 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14382426#comment-14382426
] 

Josh Elser commented on HBASE-13262:
------------------------------------

bq. I'd probably name this just callable.hasMoreResultsContext.

Happy to change that. Will do (below) testing first.

bq. So that will work right with an old client, right? It'll just not read the context and
fall back to the old logic. That's what the code does, just making sure it's something we
tested.

That's the intent, but, admittedly, I haven't explicitly tested this. I'll give it a quick
go.

> Tried to write a simple Java client again 1.1.0-SNAPSHOT.
> * Write 1M rows, each row with 1 family, and 10 qualifiers (values [0-9]), for a total
of 10M cells written
> * Read back the data from the table, ensure I saw 10M cells
> Running it against {{04ac1891}} (and earlier) yesterday, I would get ~20% of the actual
rows. Running against 1.0.0, returns all 10M records as expected.
> [Code I was running|https://github.com/joshelser/hbase-hwhat/blob/master/src/main/java/hbase/HBaseTest.java]
for the curious.
