In addition, you can use JDBC or ODBC to … Impala is designed to deliver insight on data in Apache Hadoop in real time. Use native Hadoop techniques to create data files in S3 for querying through Impala. Kudu does not allow you to alter the primary key columns after table creation. Columns may be renamed in Kudu to work around this issue. The default database is not used when you use SAS/ACCESS Interface to Impala with PROC FEDSQL.

This supports CREATE TABLE syntax to specify the default values, but more importantly this fixes the loading of Kudu tables that may have had default values set on UNIXTIME_MICROS columns, e.g. The above table creation has the effect that all inserts into the table have an implicit "sortby(day,hour)" plan hint applied. Kudu tables with a column name containing upper case or non-ascii characters may not be used as an external table in Impala. As data often lands in Hadoop continuously in certain use cases (such as time-series analysis, real-time fraud detection, real-time risk detection, and so on), it’s desirable for Impala to query this new “fast” data with minimal delay and without interrupting running […] This is my create statement for impala-shell: CREATE TABLE IF NOT EXISTS tmp.demo0011( uid Bigint, comment'用户uid' nick String, comment'昵称' primary key(uid) ) partition by hash(uid) partitions 128 stored as kudu tblproperties ( 'kudu.master_addresses'='10.10.10.1' ); When I enter desc tmp.demo0011; I get: Kudu does not allow you to update the primary key columns of a row. There are many advantages when you create tables in Impala using Apache Kudu as a storage format. Kudu tables with a name containing upper case or non-ascii characters must be assigned an alternate name when used as an external table in Impala. Kudu (currently in beta), the new storage layer for the Apache Hadoop ecosystem, is tightly integrated with Impala, allowing you to insert, query, update, and delete data from Kudu tablets using Impala’s SQL syntax, as an alternative to using the Kudu APIs to build a custom Kudu application.
