When a client determines that it is disconnected from the cluster, it assigns a new node ID to itself and tries to reconnect to the cluster.

By default only one sender link is cached which means that sending to multiple destinations will cause the cached sender to be closed and new sender to be opened each time the destination changes. Increasing the cache size can reduce the amount of times the cache swapping occurs. Setting the cache size to zero results in the sender links being closed after each send operation If you are not very familiar with Apache, then disable the modules one-by-one. After you disable each module, restart Apache to test. This is useful because when you disable some modules such as dav_module, autoindex_module, etc, then some of the related config lines in httpd.conf or apache2.conf will be left stranded. Thus, when you restart Apache, it will show errors. For example A.2.3.12 UIViewRoot Caching. Use the org.apache.myfaces.trinidad.CACHE_VIEW_ROOT parameter to enable or disable UIViewRoot caching. When token client-side state saving is enabled, MyFaces Trinidad can apply an additional optimization by caching an entire UIViewRoot tree with each token. (Note that this does not affect thread safety or session. You can modify the TTL depending on how frequently the Hive metadata is updated. If the Hive metadata is updated frequently, decrease the cache TTL value. If Hive metadata is updated infrequently, increase the cache TTL value. For example, when you run a Drill query on a Hive table, Drill refreshes the cache 60 seconds after the read on the table. If the table is updated in Hive within that 60 second window and you issue another query on the table, Drill may not be aware of the changes until.
