We are facing a problem with Imapla Column naming convention which seems unclear to us.
The CDH imapala documentation (http://www.cloudera.com/documentation/archive/impala/2-x/2-0-x/topics/impala_identifiers.html) 3rd bullet point says : An identifier must start with an alphabetic character. The remainder can contain any combination of alphanumeric characters and underscores. Quoting the identifier with backticks has no effect on the allowed characters in the name.
Now, due to dependency with the upstream SAP systems, we had to name a column name starting with (0) zero as numeric. While defining and extracting the records from the table impala does not show any semantic error. While connecting Imapala with SAP HANA through SDA (Smart Data Access), the extraction is failing for this particular column which is starting with a leading zero (0) and fine for rest of the columns which are starting with an alphabet. The error shows as "... ^ Encountered: DECIMAL LITERAL "
I have to points.
Any insight will be highly appreciable.
