Class TestMobCompactionWithDefaults

java.lang.Object

org.apache.hadoop.hbase.mob.TestMobCompactionWithDefaults

Direct Known Subclasses:

TestMobCompactionOptMode, TestMobCompactionOptRegionBatchMode, TestMobCompactionRegularRegionBatchMode

public class TestMobCompactionWithDefaults
extends Object

Mob file compaction base test. 1. Enables batch mode for regular MOB compaction, Sets batch size to 7 regions. (Optional) 2. Disables periodic MOB compactions, sets minimum age to archive to 10 sec 3. Creates MOB table with 20 regions 4. Loads MOB data (randomized keys, 1000 rows), flushes data. 5. Repeats 4. two more times 6. Verifies that we have 20 *3 = 60 mob files (equals to number of regions x 3) 7. Runs major MOB compaction. 8. Verifies that number of MOB files in a mob directory is 20 x4 = 80 9. Waits for a period of time larger than minimum age to archive 10. Runs Mob cleaner chore 11 Verifies that number of MOB files in a mob directory is 20. 12 Runs scanner and checks all 3 * 1000 rows.
