Examples of net.opentsdb.tree.Tree.flushCollisions()

net.opentsdb.tree.Tree.flushCollisions()
Attempts to flush the collisions to storage. The storage call is a PUT so it will overwrite any existing columns, but since each column is the TSUID it should only exist once and the data shouldn't change. Note: This will also clear the local {@link #collisions} map @param tsdb The TSDB to use for storage access @return A meaningless deferred (will always be true since we need to groupit with tree store calls) for the caller to wait on @throws HBaseException if there was an issue

  public void flushCollisions() throws Exception {
    setupStorage(true, true);
    final Tree tree = buildTestTree();
    tree.setStoreFailures(true);
    tree.addCollision("010203", "AABBCCDD");
    assertNotNull(tree.flushCollisions(storage.getTSDB())
        .joinUninterruptibly());
    assertEquals(4, storage.numRows());
    assertEquals(3, storage.numColumns(new byte[] { 0, 1, 1 }));
