-----------------------------------
Summary: ListHDFS processor will list files without using previous
state when cluster startup
Key: NIFI-6339
URL: https://issues.apache.org/jira/browse/NIFI-6339
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.9.2, 1.9.1, 1.9.0
Reporter: Hsin-Ying Lee
Fix For: 1.9.2, 1.9.1, 1.9.0
When the node startup, NiFi will create processor and load the property & state.
But ListHDFS will ignore the previous listed-state stored on Zookeeper, and
relist all file again.
And I found when we call the function setProperty, we only check the value
between default and newValue. If oldValue is same with newValue, it'll also
trigger function onPropertyModified.
It casue ListHDFS loaclVariable: resetState to be true. When ListHDFS be
triggered, it'll clear the state empty, and relist all the files in the
directory.
{code:java}
// AbstractComponentNode.java
if (!value.equals(propertyModComparisonValue)) {
try {
onPropertyModified(descriptor, oldValue, value);
} catch (final Exception e) {
// nothing really to do here...
}
}
{code}
