Riza Suminto commented on IMPALA-12840:
---------------------------------------
The test code access catalogd page with URL like this.
{code:java}
/catalog_object?json&object_type=TABLE&object_name=test_reuse_partitions_nontransactional_c9c4d5c9.tbl
{code}
If an exception happen, the response can contain \n char like this:
{code:java}
{
"__common__": {
"process-name": "catalogd",
"navbar": [{
"link": "/",
"title": "/"
}, {
"link": "/catalog",
"title": "/catalog"
}, {
"link": "/events",
"title": "/events"

}]
},
"error": "DatabaseNotFoundException: Database
'test_reuse_partitions_nontransactional_c9c4d5c9' not found\n"
} {code}
Looks like some error handling should be done here:
