Casey Stella updated METRON-610: -------------------------------- Fix Version/s: 0.3.1 > OnlineStatisticsProvider serialization is broken at random in the REPL > ---------------------------------------------------------------------- > > Key: METRON-610 > URL: https://issues.apache.org/jira/browse/METRON-610 > Project: Metron > Issue Type: Bug > Reporter: Casey Stella > Assignee: Casey Stella > Fix For: 0.3.1 > > Original Estimate: 1h > Remaining Estimate: 1h > > We rely on the t-digest library version 3.1 and elasticsearch brings along > 3.0. There is a small API incompatibility between the two versions (namely > the static method TDigest.createAvlTreeDigest() is available in 3.1 but not > 3.0). > If the classpath for the Stellar REPL chooses the 3.0 version of the library, > then deserialization is broken. > Strictly speaking this is not a problem of the serialized form being > incorrect, but a problem in the custom kryo serialization code in the class. > It relies on the default constructor being called and then the digest being > deserialized using the code within the t-digest library. Because the default > constructor initializes the digest via a call that does not exist in 3.0, it > breaks. The serialization logic is safe to use in both versions, but the > object can't be constructed in 3.0. > This fix directly instantiates the AvlTreeDigest, which exists in both > versions. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
