Subject RE: Data not loaded in table via ImportTSV
Date Wed, 17 Apr 2013 03:31:49 GMT
Hi Anoop,

Actually, I got confused after reading the doc. - I thought a simple importtsv command(which
also takes table name as the argument) would suffice. But as you pointed out, completebulkload
is required.

HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath` ${HADOOP_HOME}/bin/hadoop jar ${HBASE_HOME}/hbase-0.94.6.1.jar
completebulkload hdfs://cldx-1139-1033:9000/hbase/storefileoutput PRODUCTS

Thanks for the help !

Regards,
Omkar Joshi

Hi
               Have you used the tool, LoadIncrementalHFiles  after the ImportTSV?

Subject: Data not loaded in table via ImportTSV

Hi,

The background thread is this :

http://mail-archives.apache.org/mod_mbox/hbase-user/201304.mbox/%3CE689A42B73C5A545AD77332A4FC75D8C1EFBD80952@VSHINMSMBX01.vshodc.lntinfotech.com%3E

I'm referring to the HBase doc. http://hbase.apache.org/book/ops_mgt.html#importtsv

Accordingly, my command is :

HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath` ${HADOOP_HOME}/bin/hadoop jar ${HBASE_HOME}/hbase-0.94.6.1.jar
importtsv '-Dimporttsv.separator=;' -Dimporttsv.columns=HBASE_ROW_KEY,CUSTOMER_INFO:NAME,CUSTOMER_INFO:EMAIL,CUSTOMER_INFO:ADDRESS,CUSTOMER_INFO:MOBILE
 -Dimporttsv.bulk.output=hdfs://cldx-1139-1033:9000/hbase/storefileoutput CUSTOMERS hdfs://cldx-1139-1033:9000/hbase/copiedFromLocal/customer.txt

As seen, there aren't any bad lines and mapper has output 5 records(the source text file has
5 records)

But no rows are inserted in the CUSTOMERS table :

Do I need to execute some additional step(CompleteBulkLoad?) to push the data - I'm not sure
if this is required !
