Ignite cluster with persistent store enabled did not load from wal after restarting.

[Ray Liu (rayliu)]

Hi All,

I’m using Ignite version 2.1.
I opened persistent sotre by adding these configuration in the xml file 
according to https://apacheignite.readme.io/docs/distributed-persistent-store

  <property name="persistentStoreConfiguration">
    <bean class="org.apache.ignite.configuration.PersistentStoreConfiguration"/>
  </property>

Here’s the code I used to ingest data to ignite.


public class IgniteTest {
    public static void main(String[] args) throws Exception {

        try (Ignite ignite = Ignition.start("example-ignite.xml")) {

            CacheConfiguration<Integer, Person> personCacheCfg = new 
CacheConfiguration<>("person");

            personCacheCfg.setIndexedTypes(Integer.class, Person.class);

            IgniteCache<Integer, Person> personCache = 
ignite.getOrCreateCache(personCacheCfg);

            Person p1 = new Person(1, "John", "Doe", 2000);
            Person p2 = new Person(1, "Jane", "Doe", 1000);
            Person p3 = new Person(2, "John", "Smith", 1000);
            Person p4 = new Person(2, "Jane", "Smith", 2000);

            personCache.put(p1.getId(), p1);
            personCache.put(p2.getId(), p2);
            personCache.put(p3.getId(), p3);
            personCache.put(p4.getId(), p4);
        }
    }
     public static class Person implements Serializable {
        private static int PERSON_ID = 0;

        @QuerySqlField(index = true)
        private Integer id;

        @QuerySqlField(index = true)
        private Integer orgId;

        @QuerySqlField
        private String firstName;

        @QuerySqlField
        private String lastName;

        @QuerySqlField(index = true)
        private double salary;

        Person(Integer orgId, String firstName, String lastName, double salary) 
{
            id = PERSON_ID++;

            this.orgId = orgId;
            this.firstName = firstName;
            this.lastName = lastName;
            this.salary = salary;
        }

        public Integer getOrganizationId() {
            return orgId;
        }

        public String getFirstName() {
            return firstName;
        }

        public String getLastName() {
            return lastName;
        }

        public double getSalary() {

            return salary;
        }

        public Integer getId() {
            return id;
        }
    }

}

And I can see the wal log files generated under /$IgniteHome/work/db folder.
After restarting the cluster, the “person” cache should be re-created 
automatically, right?
But it didn’t.
Here’s some debug log may help locate the problem
