Known Limitations
Jetty configuration incompatibility in GridGain 8.7.21 and later
If you are upgrading from version 8.7.20 or earlier, you must take into account an incompatibility related to Jetty configuration, which was introduced in GridGain 8.7.21.
Your setup may be affected if:
-
You’re using the
ignite-rest-http
module (e.g. to connect to GridGain Web Console) -
You have a custom Jetty configuration that enables SSL for REST
-
Your Jetty configuration uses the
org.eclipse.jetty.util.ssl.SslContextFactory
class -
The keystore specified in the Jetty configuration contains both the CA certificate and the private certificate
In this case, after starting the new version, you’ll see an error similar to:
java.lang.IllegalStateException: KeyStores with multiple certificates are not supported on the base class
org.eclipse.jetty.util.ssl.SslContextFactory. (Use org.eclipse.jetty.util.ssl.SslContextFactory$Server
or org.eclipse.jetty.util.ssl.SslContextFactory$Client instead)
To workaround this issue, you need to alter the Jetty configuration to use org.eclipse.jetty.util.ssl.SslContextFactory$Server
or org.eclipse.jetty.util.ssl.SslContextFactory$Client
.
For a configuration example, see Client Certificate Authentication.
Default rebalanceThreadPoolSize
in GridGain 8.7.26 and later
In GridGain 8.7.26, the default value of the property IgniteConfiguration.rebalanceThreadPoolSize
has changed from 1
to min(4, number of CPU / 4)
.
It may cause a compatibility issue under the following conditions:
-
A Rolling Upgrade is being performed
-
The upgrade is performed from a version 8.5.7 or earlier for 8.5.x, or 8.7.3 or earlier for 8.7.x
-
The server nodes have at least 8 CPU cores
-
The nodes configuration don’t have the property
IgniteConfiguration.rebalanceThreadPoolSize
set (i.e. the default value is used)
In this case, you’ll see an error similar to
сlass org.apache.ignite.IgniteException: Rebalance configuration mismatch (fix configuration or set -DIGNITE_SKIP_CONFIGURATION_CONSISTENCY_CHECK=true system property).
Different values of such parameter may lead to rebalance process instability and hanging. [rmtNodeId=5fc58fb7-209d-489a-8034-0127a81abed6, locRebalanceThreadPoolSize = 4, rmtRebalanceThreadPoolSize = 1]
To workaround this issue, you need to change the configuration of the server nodes to set rebalanceThreadPoolSize=1
so that it matches
the old default. Example:
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="rebalanceThreadPoolSize" value="1"/>
<!-- The rest of the configuration goes here -->
</bean>
