Examples with HiveStorageFormat io.prestosql.plugin.hive.HiveStorageFormat used on opensource projects

Example 1 with HiveStorageFormat

use of io.prestosql.plugin.hive.HiveStorageFormat in project carbondata by apache.

the class CarbondataConnectorFactory method setCarbonEnum.

/**
 * Set the Carbon format enum to HiveStorageFormat, its a hack but for time being it is best
 * choice to avoid lot of code change.
 *
 * @throws Exception
 */
private static void setCarbonEnum() throws Exception {
    for (HiveStorageFormat format : HiveStorageFormat.values()) {
