HBASE-681 NPE in Memcache HAbstractScanner - remove HAbstactScanner.iterator() - iterator is not a method on InternalScanner HRegion - make getScanner more efficient by iterating only once to find the stores we need to scan - only pass columns relevant to a store to a HStoreScanner - remove HScanner.iterator() - iterator is not a method on InternalScanner Memcache, MemcacheScanner - Fix NPE in Memcache - never return HConstants.LATEST_TIMESTAMP as the timestamp value for a row. Instead use the largest timestamp from the cells being returned. This allows a scanner to determine a timestamp that can be used to fetch the same data again should new versions be inserted later. StoreFileScanner - getNextViableRow would find a row that matched the row key, but did not consider the requested timestamp. Now if the row it finds has a timestamp greater than the one desired it advances to determine if a row with a timestamp less than or equal to the requested one exists since timestamps are sorted descending. - removed an unnecessary else testScanMultipleVersions - Test program that fails on current trunk but passes when this patch is applied. git-svn-id: https://svn.apache.org/repos/asf/hadoop/hbase/trunk@670124 13f79535-47bb-0310-9956-ffa450edef68 |
