Subject [jira] [Reopened] (ATLAS-1744) Error when searching type with attribute name "order" , "limit" , "offset"
Date Sat, 29 Apr 2017 07:25:04 GMT

     [ https://issues.apache.org/jira/browse/ATLAS-1744?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Madhan Neethiraj reopened ATLAS-1744:
-------------------------------------

After introducing the validation on attributeNames to prevent use of keywords, Atlas startup
fails due to current use of one  of the reserved words - 'order' in struct hive_order. Hence
this validation should be disabled.

The original issue reported by this JIRA, error executing DSL queries that use such attributes,
can be resolved by surrounding the attribute name with backquotes - like `order`.
