John Gaskin created HAWQ-1486: --------------------------------- Summary: PANIC accessing PXF HDFS table Key: HAWQ-1486 URL: https://issues.apache.org/jira/browse/HAWQ-1486 Project: Apache HAWQ Issue Type: Bug Components: External Tables, PXF Reporter: John Gaskin Assignee: Vineet Goel Fix For: 2.3.0.0-incubating
This code doesn't catch the case when churl_init_download() returns NULL. This seems to trigger a segfault at libcurl level. {code} Looks like we failed to connect to PXF (?). Piece of code in HAWQ handling cUrl calls (pxfutils.c): 100 static void process_request(ClientContext* client_context, char *uri) 101 { 102 size_t n = 0; 103 char buffer[RAW_BUF_SIZE]; 104 105 print_http_headers(client_context->http_headers); 106 client_context->handle = churl_init_download(uri, client_context->http_headers); 107 memset(buffer, 0, RAW_BUF_SIZE); 108 resetStringInfo(&(client_context->the_rest_buf)); 109 110 /* 111 * This try-catch ensures that in case of an exception during the "communication with PXF and the accumulation of 112 * PXF data in client_context->the_rest_buf", we still get to terminate the libcurl connection nicely and avoid 113 * leaving the PXF server connection hung. 114 */ 115 PG_TRY(); 116 { 117 /* read some bytes to make sure the connection is established */ 118 churl_read_check_connectivity(client_context->handle); {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
