Change subject: [docs] Add release notes for 1.17.0 ...................................................................... Patch Set 9: (27 comments) Just went through 'New features'; will need to take another look to address the rest of the notes. Thank you so much for taking care of Kudu 1.17 release, Yingchun! http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc File docs/release_notes.adoc: http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@74 PS9, Line 74: or Drop 'or'? http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@78 PS9, Line 78: Kudu will reserve the table for a period of time (specified : by client API, or use `--default_deleted_table_reserve_seconds` master flag if not specified) after : receiving the DeleteTable request, and it's possible to recall this table before the table expired. Kudu keeps a soft-deleted table aside for a period of time (a.k.a. reservation), not purging the data yet. The table can be restored/recalled back before its reservation expires. The reservation period can be customized via Kudu client API upon soft-deleting the table. The default reservation period is controlled by the --default_deleted_table_reserve_seconds master's flag. http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@81 PS9, Line 81: Soft-delete related functions is not supported when HMS is enabled As of Kudu 1.17 release, the soft-delete functionality is not supported when HMS integration is enabled, but this should be addressed in a future release http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@84 PS9, Line 84: These columns are An auto-incrementing column is http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@94 PS9, Line 94: to define such a column which represents to represent http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@99 PS9, Line 99: . By default, the flag is set to 'false' http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@102 PS9, Line 102: authentication using JWT tokens into C++ RPC negotiation authentication of Kudu client applications to Kudu servers using JSON Web Tokens (JWT). The JWT-based authentication can be used as an alternative to Kerberos authentication for Kudu applications running at edge nodes where configuring Kerberos might be cumbersome. Similar to Kerberos credentials, a JWT is considered a primary client's credentials. http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@102 PS9, Line 102: When : the newly introduced `--enable_jwt_token_auth` is set to `true`, the server expects a valid JWT to : be sent by the client which will be verified when the connection is being established. The server-side capability of JWT-based authentication is controlled by the `--enable_jwt_token_auth` flag (set 'false' by default). When the flat set to 'true', a Kudu server is capable of authenticating Kudu clients using the JWT provided by the client during RPC connection negotiation. From its side, a Kudu client authenticates a Kudu server by verifying its TLS certificate. For the latter to succeed, the client should use Kudu client API to add the cluster's IPKI CA certificate into the list of trusted certificates. http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@106 PS9, Line 106: . So, it's now possible to dynamically scale the set of readers/scanners fetching data from a Kudu table in parallel. http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@111 PS9, Line 111: Exposed write successful/ignore count metrics for C++ and Java clients Statistics on various write operations is now available via Kudu client API at the session level http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@122 PS9, Line 122: . This might be useful in various scenarios where Kudu cluster is running in an internal network behind a firewall, but Kudu clients are running at the other side of the firewall using JWT to authenticate to Kudu servers, and the RPC traffic between to the Kudu cluster is forwarded through a TCP/SOCKS proxy. http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@126 PS9, Line 126: to reduce in reducing http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@126 PS9, Line 126: table, it is ... table.

This is useful to address various hot-spotting issues when too many tablet replicas from the same range (but different hash buckets) were placed at the same tablet server. The hot-spotting issue in tablet replica placement should be address in a follow-up releases, see link:https://issues.apache.org/jira/browse/KUDU-3476[KUDU-3476] for details. http://gerrit.cloudera.org:8080/#/c/19512/9/docs/release_notes.adoc@134 PS9, Line 134: runtime, it’s useful to reclaim ... runtime.
