python - running aws athena query via pyathena -


this query works fine in athena's front-end:

select * analysisdata."iris" limit 10;

i using python code run above query via python/pyathena

from pyathena import connect  cursor = connect(aws_access_key_id='aki.deleted.2q',                  aws_secret_access_key='d.deleted.al',                  s3_staging_dir='s3://bla887342ac-a3ce-4600-94d0-9092f4a6bd20/iris',                  region_name='eu-west-1').cursor()  cursor.execute("""select * analysisdata.""iris"" limit 10;""")  print(cursor.description) print(cursor.fetchall())

unfortunately get:

pyathena.error.databaseerror: error occurred (invalidrequestexception) when calling startqueryexecution operation: line 1:27: mismatched input '.' expecting {<eof>, ',', 'where', 'group', 'order', 'having', 'limit', 'approximate', 'join', 'cross', 'inner', 'left', 'right', 'full', 'natural', 'union', 'except', 'intersect'}

i presume introduction of:

""" , ""

any ideas?

ps:

i tried:

cursor.execute("select * analysisdata.""iris"" limit 10;")

get:

pyathena.error.operationalerror: com.facebook.presto.hive.datacatalogexception: namespace analysisdata not found. please check query.

why facebook appear in this?

i tried:

cursor.execute("select * analysisdata.iris limit 10;")

same error message ...

as appears, catalog in eu-west-1 not contain analysisdata db.

you have specify region in created database/table in athena console, rather specified s3 bucket region.

to solve that, log console, , verify region contains database/table.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
