memcache.getScanner didn't return the first row(if it exists), cause
HScannerInterface's output incorrect
---------------------------------------------------------------------------------------------------------
Key: HBASE-686
URL: https://issues.apache.org/jira/browse/HBASE-686
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.1.2
Reporter: LN
HTable.obtainScanner methods should return the start row if it exists, although
HTable's javadoc didn't clearly desc. but i found the result of htable scanners
sometimes contain the start row, sometimes not.
after more testing and code review, i found it should be a bug in
HStore.Memcache.MemcacheScanner. in the constructor it set this.currentRow =
firstRow, but when doing next(), there's a this.currentRow =
getNextRow(this.currentRow) before fetch result.
