all the features required for your use case, otherwise, continue to use Sqoop

Use the following combination of Sqoop and Hadoop:
Hadoop 2.0.0 CDH 4.6Sqoop 1.4.3 CDH 4.6
2. Regarding import into local filesystem, specify the target directory with
hdfs: --target-dir
"hdfs://finattr-comp-dev-01:9999/apps/sas/hive/warehouse/<table>"

the data load work somehow but I don’t think it’s the right way ! Here is what
I tried (sorry for the long email) 1. Hadoop 2.5.1 +
sqoop-1.4.5.bin__hadoop-2.0.4-alpha : This failed with the following error. I
did see same issue asked on stackoverflow but no fix. This is most likely due
to some jar files mismatch. Note:
/tmp/sqoop-sas/compile/1ee9265317c9d91a077060f857c3e726/TEMP_ADDRESS.java uses
or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for
details. 14/11/24 23:05:43 INFO orm.CompilationManager: Writing jar file:
/tmp/sqoop-sas/compile/1ee9265317c9d91a077060f857c3e726/TEMP_ADDRESS.jar
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/mapreduce/InputFormat at
java.lang.ClassLoader.defineClass1(Native Method) 2. Hadoop 2.5.1 +
sqoop-1.4.5.bin__hadoop-1.0.0 : This also failed with some Class version
mismatch error. So I downloaded the Hadoop_1.2.1 also and specified that as the
HADOOP_MAPRED_PATH in the Sqoop configuration (to pick up the hadoop_core.jar).
This worked for both HDFS and Hive imports from OracleJ However there are 2
issues 2.1 : I don’t want to maintain 2 versions of Hadoop 2.2 : The imported
file is not actually going on the HDFS that I have setup, instead going on
thelocal file system. For example when I load a file in a Hive table in “hive”,
it is visible on
'hdfs://finattr-comp-dev-01:9999/apps/sas/hive/warehouse/<table> whereas with
the Sqoop import the file is landing in /apps/sas/hive/warehouse/<table>.
Thanks - Atul
