Subject [jira] [Commented] (HBASE-13262) ResultScanner doesn't return all rows in Scan
Date Tue, 17 Mar 2015 21:31:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14366126#comment-14366126
] 

Andrew Purtell commented on HBASE-13262:
----------------------------------------

bq. Note that to run the scan with this configuraiton you must remove the ArrayList presizing
that is performed in RSRpcServices on line 2055. The caching value is used to presize the
array and thus you will likely run into OOME if you do not remove the presizing when running
this configuration

That's an issue in 0.98 too, see HBASE-13269 to follow up

> 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.
