Add Statement Options

BLOCKSIZE=

specifies the block size to use for distributing the data set. Suffix values are B (bytes), K (kilobytes), M (megabytes), and G (gigabytes). The default block size is 32M.

Alias

BLOCK=

COPIES=

specifies the number of replications to make for the data set (beyond the original blocks). The default value is 2 when the INNAMEONLY option is specified and otherwise is 1. Replicated blocks are used to provide fault tolerance for HDFS. If a machine in the cluster becomes unavailable, then the blocks needed for the SASHDAT file can be retrieved from replications on other machines.

Alias

COPY=

(input-data-set-options)

specifies any data set options to apply to the input data set.

Typically, you specify a description for the data set with the LABEL= option. The LABEL= option assigns the description to the SASHDAT file when the data set is stored in HDFS. The LABEL= option is used to override the label that is associated with the data set. Enclose the options in parentheses.

PATH='HDFS-path'

specifies the directory in HDFS in which to store the SASHDAT file. The value is case sensitive. The filename for the SASHDAT file that is stored in the path is always lowercase.

Alias

OUTDIR=

REPLACE

specifies that the SASHDAT file should be overwritten if it already exists.

Alias

OVERWRITE

VARS=(<variables>)

specifies the variables from the input data set to include in the SASHDAT file that is stored to HDFS. The default action is to include all the variables from the input data set.
