Example 76 with TableDescriptor

use of org.apache.hadoop.hbase.client.TableDescriptor in project hbase by apache.

the class TestMultiVersions method testTimestamps.

/**
 * Tests user specifiable time stamps putting, getting and scanning.  Also
 * tests same in presence of deletes.  Test cores are written so can be
 * run against an HRegion and against an HTable: i.e. both local and remote.
 *
 * <p>Port of old TestTimestamp test to here so can better utilize the spun
 * up cluster running more than a single test per spin up.  Keep old tests'
 * crazyness.
