[jira] [Commented] (KAFKA-9775) IllegalFormatConversionException
from kafka-consumer-perf-test.sh
[ https://issues.apache.org/jira/browse/KAFKA-9775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17068581#comment-17068581 ]

---------------------------------------
tombentley commented on pull request #8373: KAFKA-9775: Fix IllegalFormatConversionException in ToolsUtils
URL: https://github.com/apache/kafka/pull/8373
The runtime type of Metric.metricValue() needn't always be a Double,
for example, if it's a gauge from IntGaugeSuite.
Since it's impossible to format non-double values with 3 point precision
IllegalFormatConversionException resulted.
