How Do I Deal with the Restrictions of the Phoenix BulkLoad Tool?

Question

When the indexed field data is updated, if a batch of data exists in the user table, the BulkLoad tool cannot update the global and partial mutable indexes.

Answer

Problem Analysis

  1. Create a table.
    CREATE TABLE TEST_TABLE(
    DATE varchar not null,
    NUM integer not null,
    SEQ_NUM integer not null,
    ACCOUNT1 varchar not null,
    ACCOUNTDES varchar,
    FLAG varchar,
    SALL double,
    CONSTRAINT PK PRIMARY KEY (DATE,NUM,SEQ_NUM,ACCOUNT1)
    );
  2. Create a global index.

    CREATE INDEX TEST_TABLE_INDEX ON TEST_TABLE(ACCOUNT1,DATE,NUM,ACCOUNTDES,SEQ_NUM);

  3. Insert data.

    UPSERT INTO TEST_TABLE (DATE,NUM,SEQ_NUM,ACCOUNT1,ACCOUNTDES,FLAG,SALL) values ('20201001',30201001,13,'367392332','sffa1','','');

  4. Execute the BulkLoad task to update data.
    hbase org.apache.phoenix.mapreduce.CsvBulkLoadTool -t TEST_TABLE -i /tmp/test.csv, where the content of test.csv is as follows:

    20201001

    30201001

    13

    367392332

    sffa888

    1231243

    23

  5. Symptom: The existing index data cannot be directly updated. As a result, two pieces of index data exist.
    +------------+-----------+-----------+---------------+----------------+
    | :ACCOUNT1  |   :DATE   |   :NUM    | 0:ACCOUNTDES  | :SEQ_NUM  |
    +------------+-----------+-----------+---------------+----------------+
    | 367392332  | 20201001  | 30201001  | sffa1          |  13                    |
    | 367392332  | 20201001  | 30201001  | sffa888       | 13                    |
    +------------+-----------+-----------+---------------+----------------+

Solution

  1. Delete the old index table.

    DROP INDEX TEST_TABLE_INDEX ON TEST_TABLE;

  2. Create an index table in asynchronous mode.

    CREATE INDEX TEST_TABLE_INDEX ON TEST_TABLE(ACCOUNT1,DATE,NUM,ACCOUNTDES,SEQ_NUM) ASYNC;

  3. Recreate a index.

    hbase org.apache.phoenix.mapreduce.index.IndexTool --data-table TEST_TABLE --index-table TEST_TABLE_INDEX --output-path /user/test_table
