Satish Mittal commented on OOZIE-1741: -------------------------------------- Thanks [~thiruvel] for your inputs! - For 1), we already have an EL dataInPartitionFilter(). - For 2), the proposed EL in this jira dataInPartitions() can serve the purpose. - For 3), I think we should add new ELs as per the requirement, since a large number of combinations are possible here (comparator:- =, !=, <, > etc and separator:- AND, OR). The use-case of 3) is closer to 1) since it aims to generate a filter criteria, as against 2) which aims to generate the value of a partition spec to be used in DDL/import/export queries. I checked that in Hive, the format of partition spec in various DDL queries (alter, truncate, drop, show, describe), DML queries (load, insert) is: (partcol1=val1, partcol2=val2 ...). The format of partition spec for IMPORT/EXPORT queries is: (partcol1="val1", partcol2="val2" ...). I verified that the latter format is a super-set, i.e. specifying (partcol1="val1", partcol2="val2" ...) works for all these queries. That is the format generated by EL dataInPartitions() in this patch as well. Regarding partial/full partition spec, even the existing EL dataInPartitionSpec writes all partition cols specified in HCat URI for dataset. The same approach is taken for EL dataInPartitions() introduced in this patch. [~rohini], can you provide your comments here? > Add new coord EL function to get input partitions value string > -------------------------------------------------------------- > > Key: OOZIE-1741 > URL: https://issues.apache.org/jira/browse/OOZIE-1741 > Project: Oozie > Issue Type: Improvement > Reporter: Satish Mittal > Assignee: Satish Mittal > Attachments: OOZIE-1741-v2.patch, OOZIE-1741-v3.patch, > OOZIE-1741.patch.txt > > > Currently oozie provides coord EL functions to get partition filter string > (where key-values are separated by AND) for various action types - > java/pig/hive.
