Examples with StoreConfigInformation org.apache.hadoop.hbase.regionserver.StoreConfigInformation used on opensource projects

Example 1 with StoreConfigInformation

use of org.apache.hadoop.hbase.regionserver.StoreConfigInformation in project hbase by apache.

the class TestStripeCompactionPolicy method createPolicy.

private static StripeCompactionPolicy createPolicy(Configuration conf, long splitSize, float splitCount, int initialCount, boolean hasTtl) throws Exception {
    conf.setLong(StripeStoreConfig.SIZE_TO_SPLIT_KEY, splitSize);
    conf.setFloat(StripeStoreConfig.SPLIT_PARTS_KEY, splitCount);
    conf.setInt(StripeStoreConfig.INITIAL_STRIPE_COUNT_KEY, initialCount);
    StoreConfigInformation sci = mock(StoreConfigInformation.class);
    when(sci.getStoreFileTtl()).thenReturn(hasTtl ? defaultTtl : Long.MAX_VALUE);
    StripeStoreConfig ssc = new StripeStoreConfig(conf, sci);
    return new StripeCompactionPolicy(conf, sci, ssc);
}

Example 2 with StoreConfigInformation

use of org.apache.hadoop.hbase.regionserver.StoreConfigInformation in project hbase by apache.

the class TestStripeCompactionPolicy method testSingleStripeCompaction.
