Fixes#5612, #5573 and #5518.
Using the MetaExecuter, queries that need to run on both data nodes
and optionally the meta store will be executed across all data nodes
in the cluster.
This fixes a regression introduced in #5757 due to the node.ID getting
assigned by both the meta and data services. When both roles are active,
the data CreateDataNode path was not getting called because a node ID was
already assigned.
This fixes the issue by seeing if a DataNode already exists for our node
ID, and if it does not, we create one.
This fixes a couple of issues with starting meta-only nodes.
1. We were always calling CreateDataNode regardless of whether the the
node is running data services. We only call that now when node is
data enabled.
2. The node.json was created along-side creating the data node. Since
we are not creatinga a data node, this didn't happen anymore. There
wasn't a simple way to do this in one place so it's actually handle
for when creating a meta or a data node now. Since the ID assigned
to the node is the same regardless of role this works in all combinations
of roles.
3. The JoinMetaServer didn't return the ID of the joining node which
created some races when multiple nodes were joining. The join call now
returns that information to the caller.
Fixes#5754
The join option was incorrectly exposed on the meta config. It should
be at the top-level as a string and propogate down to the meta config
as a slice.
This fixes several issues related to the bind address and hostname:
* Allows bind addresses where a hostname or IP is not specified to
work correct and bind to all interfaces by default.
* Fixes the top-level "hostname" config option to allow overridding
all bind address hostnames. This allows a node to advertise a different
hostname than what is defined in the bind address setting.
* Adds the -hostname command-line option back to allow specifing
both -join and -hostname as command-line flags.
* Enforces a configuration precedence and overriding ability defined
as config file is overridden by env vars which are overriden by command-line
flags.
Fixes#5670#5671
The name of the column will be every measurement located inside of the
math expression in the order they are encountered in within the
expression.
Also handle `*influxql.ParenExpr` in the function
`(*influxql.Field).Name()`
Fixes#5730.
Previously, meta.Client would drop the default retention policy when
trying to create a database with a retention policy. The RPC has now
been modified to include the desired retention policy in the
CreateDatabase command and have it use that retention policy information
instead of the default configuration when provided.
This also lowers the number of RPC calls for
CreateDatabaseWithRetentionPolicy to only a single RPC call instead of
two.
Protections have also been included so creating a retention policy with
different parameters will return an error similar to if you tried to
modify the retention policy separately.
Fixes#5696.
A case (#5606) was found where a lot of data unexpectedly disappeared from a database
following a TSM conversion.
The proximate cause was an inconsistency between the root Bolt DB bucket list
and the meta data in the "series" bucket of the same shard. There were apparently valid
series in Bolt DB buckets that were no longer referenced by the meta data
in the "series" bucket - so-called orphaned series; since the conversion
process only iterated across the series found in the meta data, the conversion process
caused the orphaned series to be removed from the converted shards. This resulted in the
unexpected removal of data from the TSM shards that had previously been accessible
(despite the meta data inconsistency) in the b1 shards.
The root cause of the meta data inconsistency in the case above was a failure, in versions prior
to v0.9.3 (actually 3348dab) to update the "series" bucket with series that had been created in
previous shards during the life of the same influxd process instance.
This fix is required to avoid data loss during TSM conversions for shards that were created with
versions of influx that did not include 3348dab (e.g. prior to v0.9.3).

This removes the MetaServers property from node.json to eliminate one
of the four places those addresses are stored on disk. We always use
the values that come through the config (via file, env var or -join arg).
