Goden Yao created HAWQ-932:
------------------------------
Summary: HAWQ fails to query external table defined with
"localhost" in URL
Key: HAWQ-932
URL: https://issues.apache.org/jira/browse/HAWQ-932
Project: Apache HAWQ
Issue Type: Bug
Components: External Tables, PXF
Reporter: Goden Yao
Assignee: Goden Yao
Originally reported by [~jpatel] when he's making a docker image based on HAWQ
2.0.0.0-incubating dev build. Investigated by [~odiachenko]
There is workaround to define it with 127.0.0.1, but there is not a workaround
for querying tables using HCatalog integration.
It used to work before.
{code}
template1=# CREATE EXTERNAL TABLE ext_table1 (t1 text, t2 text,
num1 integer, dub1 double precision) LOCATION
(E'pxf://localhost:51200/hive_small_data?PROFILE=Hive') FORMAT 'CUSTOM'
(formatter='pxfwritable_import');*
CREATE EXTERNAL TABLE
template1=# select * from ext_table1;
ERROR: remote component error (0): (libchurl.c:898)*
When I turned on debug mode in curl, I found this error in logs - "*
Closing connection 0".
I found a workaround, to set CURLOPT_RESOLVE option in curl:
{code}
struct curl_slist *host = NULL;
host = curl_slist_append(NULL, "localhost:51200:127.0.0.1");*
set_curl_option(context, CURLOPT_RESOLVE, host);
{code}
It seems like an issue with DNS cache,
