Validating import results in a cluster

View the results of an import in the Cassandra File System.

Use this command to view the results in the Cassandra File System:

./dse hadoop fs -ls /npa_nxx

Depending on the number of DataStax Enterprise analytics nodes and task tracker configuration, the output shows a number of files in the directory, part-m-0000n, where 'n' ranges from 0 to the number of tasks that were executed as part of the Hadoop job.

The contents of these files can be viewed using this command:

./dse hadoop fs -cat /npa_nxx/part-m-00000

By varying the number of tasks (the 00000), the output looks something like this:

361991,361,991,27.73,097.40,L,TX,Corpus Christi
361992,361,992,27.73,097.40,L,TX,Corpus Christi
361993,361,993,27.73,097.40,L,TX,Corpus Christi
361994,361,994,27.73,097.40,L,TX,Corpus Christi
361998,361,998,27.79,097.90,L,TX,Agua Dulce
361999,361,999,27.80,097.40,W,TX,Padre Island National Seashore

As shown in the output, the CSV file format that Sqoop requires does not include optional spaces in the delimiter.
