Example 1 with GetPartitionNamesPsRequest

use of org.apache.hadoop.hive.metastore.api.GetPartitionNamesPsRequest in project hive by apache.

the class Hive method getPartitionNames.

public List<String> getPartitionNames(String dbName, String tblName, Map<String, String> partSpec, short max) throws HiveException {
    List<String> names = null;
    Table t = getTable(dbName, tblName);
    List<String> pvals = MetaStoreUtils.getPvals(t.getPartCols(), partSpec);
    try {
        GetPartitionNamesPsRequest req = new GetPartitionNamesPsRequest();
        req.setTblName(tblName);
        req.setDbName(dbName);
        req.setPartValues(pvals);
        req.setMaxParts(max);
        if (AcidUtils.isTransactionalTable(t)) {
            ValidWriteIdList validWriteIdList = getValidWriteIdList(dbName, tblName);
            req.setValidWriteIdList(validWriteIdList != null ? validWriteIdList.toString() : null);
            req.setId(t.getTTable().getId());
        }
        GetPartitionNamesPsResponse res = getMSC().listPartitionNamesRequest(req);
        names = res.getNames();
    } catch (NoSuchObjectException nsoe) {
        // listPartitionNames() throws NoSuchObjectException to indicate null partitions
        return Lists.newArrayList();
    } catch (Exception e) {
