Modifier and Type | Field and Description |
---|---|
static java.lang.String |
PARTAGG_MINREDUCTION
Controls the minimum reduction in-mapper Partial Aggregation should achieve in order
to stay on.
|
static java.lang.String |
PIG_DEFAULT_LOAD_FUNC
This key is used to define the default load func.
|
static java.lang.String |
PIG_DEFAULT_STORE_FUNC
This key is used to define the default store func.
|
static java.lang.String |
PIG_ENABLE_TEMP_FILE_COMPRESSION
This key is used to define whether to have intermediate file compressed
|
static java.lang.String |
PIG_INTERSTORAGE_SYNCMARKER_INTERVAL
Defines the interval (in bytes) when a sync marker should be written into the binary file
|
static long |
PIG_INTERSTORAGE_SYNCMARKER_INTERVAL_DEFAULT |
static java.lang.String |
PIG_INTERSTORAGE_SYNCMARKER_SIZE
Sets the length of record markers in binary files produces by Pig between jobs
The longer the byte sequence means less chance of collision with actual data,
shorter sequence means less overhead
|
static int |
PIG_INTERSTORAGE_SYNCMARKER_SIZE_DEFAULT |
static int |
PIG_INTERSTORAGE_SYNCMARKER_SIZE_MAX |
static int |
PIG_INTERSTORAGE_SYNCMARKER_SIZE_MIN |
static java.lang.String |
PIG_OUTPUT_COMMITTER_RECOVERY
This key is used to define whether to support recovery to handle the
application master getting restarted.
|
static java.lang.String |
PIG_STORE_SCHEMA_DISAMBIGUATE
If set to false, automatic schema disambiguation gets disabled i.e.
|
static java.lang.String |
PIG_STORE_SCHEMA_DISAMBIGUATE_DEFAULT |
static java.lang.String |
PIG_STREAMING_ENVIRONMENT
This key can be used to defined what properties will be set in the streaming environment.
|
static java.lang.String |
PIG_TEMP_FILE_COMPRESSION_CODEC
Compression codec used by intermediate storage
TFileStorage only support gzip and lzo.
|
static java.lang.String |
PIG_TEMP_FILE_COMPRESSION_STORAGE
This key is used to set the storage type used by intermediate file storage
If pig.tmpfilecompression, default storage used is TFileStorage.
|
static java.lang.String |

cached bags.
|
static java.lang.String |

static java.lang.String |
SHOULD_USE_SCHEMA_TUPLE
This key must be set to true by the user for code generation to be used.
|
static java.lang.String |
TIME_UDFS_PROP
Controls whether execution time of Pig UDFs should be tracked.
