how to build HDFS path to load data from ?!?!?!

Hi,

 

I have a 'simple' usecase (I thought it is simple 😉 ).

I want to call a hive script with a parameter in format YYYY-MM-DD. Inside the script I want to load data from HDFS path /a/b/c/d_${parameter}

 

How to build the path dynamically to be able to place it into LOAD DATA INPATH '...' OVERWRITE INTO TABLE data_staging;

 

Even setting the path to a variable (hardcoded) and place it as INPATH doesn't work ?!?!

 

I tried:

 

set p="/a/b/c/d_2013-07-08/data.tsv";
LOAD DATA INPATH "${hiveconf:p}" OVERWRITE INTO TABLE data_staging;

=> Error while compiling statement: FAILED: ParseException line 1:19 mismatched input '/' expecting INTO near '""' in load statement

 

If I remove the quotes from the parameter placeholder I receive an error, too. File not found, even if it does exist in HDFS, for sure, I checked it many times...

 

set p="/a/b/c/d_2013-07-08/data.tsv";
LOAD DATA INPATH ${hiveconf:p} OVERWRITE INTO TABLE data_staging;

=> Error while compiling statement: FAILED: SemanticException Line 1:17 Invalid path '"/a/b/c/d_2013-07-08/data.tsv"': No files matching path hdfs://nameservice1/a/b/c/d_2013-07-08/data.tsv

 

How can I build the path variable inside the hive script to be able to load data files from that path ?

I want to pass the day as parameter and read files from HDFS path /a/b/c/d_YYYY-MM-DD/

 

thanks in advance...

 

PS: using latest CDH5.0.1

sorry for bothering 😉

 

Issue has been solved, the error was the result of "work in concurrency" of many people in the same folder. Thereby the message "file not found" did make sense....
