HBaseStorage: how to extract columns with non ASCII characters in their name ?

[Vincent Barat <vi...@gmail.com>]

Hello,

I face a difficult issue: I need to extract some data from HBase 
columns whose names include non ASCII characters like "Cinéma" or 
event white spaces " " and coma ",".

exemple:

activity = LOAD 'hbase://activity' USING HBaseStorage('data:Cinéma') 
AS (cinema:chararray);

This line is not rejected by grunt, but does not do the job, as if 
the "data:Cinéma" column was not in my HBase table.

When I scan the table with the HBase shell, I got the following output:

1276366750803/c849058758bac column=data:Cin\xC3\xA9mas, 
timestamp=1276367292195, value=1
  1b01b3bb77215b53922

Do you see any character encoding mismatch there ?


Thanks a lot for your help.

No, the issue does not come from the missing "s" in "Cinéma" !
This typo is in the email only, not in my tests :-)
