Gian Merlino e9c3d3e651 SystemSchema: Fix data types for various fields. (#6642)
* SystemSchema: Fix data types for various fields.

- segments: start, end, partition_num
- servers: plaintext_port, tls_port
- tasks: plaintext_port, tls_port

The declared and actual types did not match, but they must or
else queries may generate ClassCastExceptions.

Also adjusted some of the code for generating values to be more
robust in the face of nulls or malformed strings.

* Fix style.

Apache Druid (incubating)

Apache Druid (incubating) is a high performance analytics data store for event-driven data.

Disclaimer: Apache Druid is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Community

The Druid community is in the process of migrating to Apache by way of the Apache Incubator. Eventually, as we proceed along this path, our site will move from http://druid.io/ to https://druid.apache.org/.

Community support is available on the druid-user mailing list(druid-user@googlegroups.com), which is hosted at Google Groups.

Development discussions occur on dev@druid.apache.org, which you can subscribe to by emailing dev-subscribe@druid.apache.org.

We also have a couple people hanging out on IRC in #druid-dev on irc.freenode.net.
