Stack : Installed HDP-2.3.2.0-2950 using Ambari 2.1 The source DB schema is on sql server and it contains several tables which either have primary key as : A varchar Composite - two varchar columns or one varchar + one int column or two int columns. There is a large table with ? rows which has three columns in the PK one int + two varchar columns As per the Sqoop documentation : Sqoop cannot currently split on multi-column indices. If your table has no index column, or has a multi-column key, then you must also manually choose a splitting column. The first question is : What is expected by 'manually choose a splitting column' - how can I sacrifice the pk and just use one column or am I missing some concept ? I proceeded with the import, the source table has 7909097 records : sqoop import --connect 'jdbc:sqlserver://somedbserver;database=somedb' --username someusname --password somepass --as-textfile --fields-terminated-by '|&|' --table ChassiECU --num-mappers 8 --warehouse-dir /dataload/tohdfs/reio/odpdw/may2016 --verbose The worrisome warnings and the incorrect mapper inputs and records : 16/05/13 10:59:04 WARN manager.CatalogQueryManager: The table ChassiECU contains a multi-column primary key. Sqoop will default to the column ChassiNo only for this job.
16/05/13 10:59:08 WARN db.TextSplitter: Generating splits for a textual index column.
16/05/13 10:59:08 WARN db.TextSplitter: If your database sorts in a case-insensitive order, this may result in a partial import or duplicate records.
16/05/13 10:59:08 WARN db.TextSplitter: You are strongly encouraged to choose an integral split column.

15818167 Surprisingly, I got either accurate or a mismatch of less than 10 records if the composite key consisted of an int(which was used for splitting) but I am still apprehensive about those as well ! How shall I proceed ?

I am novice to data loading and Avro so I can't verify the avro schema etc. provided in the post but I did face the same issue (java.io.IOException: java.io.IOException: Not a data file). I am listing below the steps I carried out to load a sql server table to avro and then to a Hive external table, maybe, it will provide some pointers : --create dir. for sqoop import [hdfs@l1031lab root]$ hadoop fs -mkdir -p /dataload/tohdfs/reio/odpdw/may2016/

I think I have found the root cause - the .avsc file is created in the tmp dir. and results in error while moving but I will put this in a separate post and once that is solved, will resume this.

Yeah even I share your opinion. I am uncomfortable with installing any new tools on the cluster machines, I did find jars like /usr/hdp/2.3.2.0-2950/sqoop/lib/avro-mapred-1.7.5-hadoop2.jar and /usr/hdp/2.3.2.0-2950/pig/lib/avro-tools-1.7.5-nodeps.jar but I am unable to find the classes/commands to be used merely to view the avro files already present on HDFS.
