Problems in running Hive queries

Question

I have configured Hadoop and Hive on Windows through Cygwin. But I am facing some problems like:

in hive terminal (CLI):

hive>

When I enter query, the query do not execute and terminal remains busy.

If I enter the query like:

bin/hive -e 'LOAD DATA INPATH 'kv1.txt' OVERWRITE INTO TABLE pokes;'

The Output is like this:

Hive history file=/tmp/Bhavesh.Shah/hive_job_log_Bhavesh.Shah_201111301549_1377455380.txt
FAILED: Parse Error: line 1:17 mismatched input 'kv1' expecting StringLiteral near 'INPATH' in load statement

What could be the problem?

Answer 1

Try

bin/hive -e 'LOAD DATA INPATH kv1.txt OVERWRITE INTO TABLE pokes;'

without the single quotes around kv1.txt.

Answer 2

If your file on the local file system try

bin/hive -e 'LOAD DATA LOCAL INPATH kv1.txt OVERWRITE INTO TABLE pokes;'

By default it looks for the file in HDFS.

Answer 3

If your file on the local file system try

bin/hive -e 'LOAD DATA LOCAL INPATH give absolute localpath OVERWRITE INTO TABLE pokes;'

If your file on the HDFS file system try

bin/hive -e 'LOAD DATA LOCAL INPATH give absolute HDFS path OVERWRITE INTO TABLE pokes;'
