2021-12-23 DSPOP-4204 Upgrade fails when root's shell is set to nologin
2021-10-05 DSPOP-4205 Pulsar connector: When you create a connection to Apache Pulsar, the server_ca_certificate argument is labeled as optional but is required. If you leave this field blank, pipeline activation fails with error "Failed to fetch".

Edit the Pulsar connection and upload the original CA certificate.
2021-10-04 DSPOP-4206 Centos: The sudo ./scloud login command does not work on Centos operating systems.

Log in to SCloud without sudo: ./scloud login.
2021-05-27 DSPOP-4207 While upgrading, the upgrade process is killed and ./gravity status returns collecting_garbage status for your cluster.

Run following command on DSP master console:

./sudo gravity plan complete

2021-05-26 DSPOP-5293 Multi node clusters do not work on certain RHEL versions running on VMWare

A regression introduced into the RHEL 8.3 linux kernel prevents multi node DSP clusters from working properly on VMWare infrastructure when the DSP VMs are scheduled across multiple ESX hosts.

This regression also exists in RHEL 8.6.

To workaround, disable checksum offloading for impacted DSP network interfaces. ethtool -K cni0 tx off ethtool -K flannel.1 tx off

Note: this must be run on every node in the cluster and every system boot. The system should recover within a few minutes.

More information about the nature of the issue is found at https://access.redhat.com/solutions/5881451

2021-04-27 DSPOP-4208 When you try to send data to an Amazon S3 bucket that has a period (.) in its name, the pipeline fails to send the data and restarts indefinitely.
2021-04-09 DSPOP-4209 When you modify a Union function using the UI Form, the pipeline canvas does not automatically update to show your changes.

Refresh the pipeline canvas by doing any of the following: save the pipeline, add a function, delete a function, or rename a function in the pipeline.
2021-02-02 DSPOP-4219 Upgrades time out due to pods in ContainerCreating status.

1. Restart the Kubelet service by running the following command: gravity exec systemctl restart kube-kubelet

2. Resume the upgrade: gravity plan resume

3. Wait for the upgrade to complete: gravity plan --tail

4. Run the post-upgrade steps: ./post-upgrade

2020-10-05 DSPOP-4481 Large batch size when using a clustered KV Store behind a GCP load balancer causes HTTPs requests to exceed allowed size (status code 431).

Reduce the batch size limit to make the request under 16KB.
2020-08-17 DSPOP-4463 DSP does not run on an operating system that has FIPS mode enabled.
2020-07-16 DSPOP-4212 Forwarders routing through DSP will not appear in the Monitoring Console Forwarder Deployment dashboards.
2020-05-06 DSPOP-4213 Custom UI for the Select function does not work when the incoming data schema contains a field name that requires single quotes.

1. Click on the SPL expressions table at the top right corner of the select function's configuration panel.

2. Input the field names with/without quotes into the editor box as valid SPL statements like 'offset' as kafka_offset.

3. Multiple entries could be added by the add button below.

2020-04-21 DSPOP-4214 You cannot switch between the Canvas and the SPL Builder if the functions are not configured correctly.

Configure every function so that the UPL is valid.
2020-04-01 DSPOP-4215 Some services fail to run on Ubuntu 16.04 with old kernels.

1. Update your Ubuntu kernel packages to the most recent available.

Run this command on each node in the cluster: apt update && apt upgrade -y && apt dist-upgrade -y

2. Reboot each node in the cluster to ensure the new kernel is running.

2020-03-27 DSPOP-4216 Stopping and starting an S3 sink pipeline leaves behind unfinalized _part files.
