Hello, Thankyou for your reply. I have attached a text file containing the data within the server.properties file.
Also I could see that it was the .log files within the __consumer_offset topic that were sizing around 100 mb each. So due to many such log files,the disk is getting maxed out. Your comments on the same. Regards, Kaushik Nambiar On Mon, Sep 24, 2018, 5:06 PM M.

The following configurations control the flush of data to disk. # There are a few important trade-offs here: # 1. Durability: Unflushed data may be lost if you are not using replication. # 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush. # 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to exceessive seeks. # The settings below allow one to configure the flush policy to flush data after a period of time or # every N messages (or both). This can be done globally and overridden on a per-topic basis. # The number of messages to accept before forcing a flush of data to disk #log.flush.interval.messages=10000 # The maximum amount of time a message can sit in a log before we force a flush #log.flush.interval.ms=1000 ############################# Log Retention Policy ############################# # The following configurations control the disposal of log segments. The policy can # be set to delete segments after a period of time, or after a given size has accumulated. # A segment will be deleted whenever *either* of these criteria are met. Deletion always happens # from the end of the log. # The minimum age of a log file to be eligible for deletion log.retention.hours=720 # A size-based retention policy for logs. Segments are pruned from the log as long as the remaining # segments don't drop below log.retention.bytes. log.retention.bytes=251658240 # The maximum size of a log segment file. When this size is reached a new log segment will be created. log.segment.bytes=1073741824 # The interval at which log segments are checked to see if they can be deleted according # to the retention policies log.retention.check.interval.ms=300000 # By default the log cleaner is disabled and the log retention policy will default to just delete segments after their retention expires. # If log.cleaner.enable=true is set the cleaner will be enabled and individual logs can then be marked for log compaction. log.cleaner.enable=false ############################# Zookeeper ############################# # Zookeeper connection string (see zookeeper docs for details). # This is a comma separated host:port pairs, each corresponding to a zk # server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002". # You can also append an optional chroot string to the urls to specify the # root directory for all kafka znodes. zookeeper.connect=x.x.x.x:2181,x.x.x.x:2181,x.x.x.x:2181 # Timeout in ms for connecting to zookeeper zookeeper.connection.timeout.ms=2000 listeners=PLAINTEXT://x.x.x.x:9092,SSL://x.x.x.x:9093 advertised.listeners=PLAINTEXT://x.x.x.x:9092,SSL://x.x.x.x:9093 ssl.keystore.location=xxxxxxxxxxxxxxxxxx ssl.keystore.password=xxxxxxxxxxxxxxxxxxxxxxx ssl.key.password=xxxxxxxxxxxxxxxxxxxxx ssl.truststore.location=xxxxxxxx ssl.truststore.password=xxxxxxxxxxxx ssl.client.auth=required security.inter.broker.protocol=SSL authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer allow.everyone.if.no.acl.found=false super.users=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx auto.create.topics.enable=false controlled.shutdown.enable=true
