Description

A table for which a user was granted 'RW' permission. Now when we want to revoke its 'W' permission only, code removes the user itself from that table permissions.
Below is the test code which reproduces the issue.

@Test(timeout = 180000)
  public void testRevokeOnlySomePerms() throws Throwable {
    TableName name = TableName.valueOf("testAgain");
    HTableDescriptor htd = new HTableDescriptor(name);
    HColumnDescriptor hcd = new HColumnDescriptor("cf");
    htd.addFamily(hcd);
    createTable(TEST_UTIL, htd);
    TEST_UTIL.waitUntilAllRegionsAssigned(name);

    try (Connection conn = ConnectionFactory.createConnection(conf)) {
      AccessControlClient.grant(conn, name, USER_RO.getShortName(), null, null, Action.READ, Action.WRITE);
      ListMultimap<String, TablePermission> tablePermissions = AccessControlLists.getTablePermissions(conf, name);
      // hbase user and USER_RO has permis
      assertEquals(2, tablePermissions.size());

      AccessControlClient.revoke(conn, name, USER_RO.getShortName(), null, null, Action.WRITE);
      tablePermissions = AccessControlLists.getTablePermissions(conf, name);
      List<TablePermission> userPerm = tablePermissions.get(USER_RO.getShortName());
      assertEquals(1, userPerm.size());

    } finally {
      deleteTable(TEST_UTIL, name);
    }
  }
