Example 1 with JDODataStoreException

use of javax.jdo.JDODataStoreException in project hive by apache.

the class Hive method getPartition.

/**
   * Returns partition metadata
   *
   * @param tbl
   *          the partition's table
   * @param partSpec
   *          partition keys and values
   * @param forceCreate
   *          if this is true and partition doesn't exist then a partition is
   *          created
   * @param partPath the path where the partition data is located
   * @param inheritTableSpecs whether to copy over the table specs for if/of/serde
   * @param newFiles An optional list of new files that were moved into this partition.  If
   *                 non-null these will be included in the DML event sent to the metastore.
   * @return result partition object or null if there is no partition
   * @throws HiveException
